Change this fraction to a percent.
fraction numerator 3 over denominator 20 end fraction
To convert a fraction to a percent, you can multiply the fraction by 100.
The fraction is 3/20.
To convert this fraction to a percent, you can multiply by 100:
(3/20) * 100 = 15
So, the fraction 3/20 is equal to 15%.
Claire got 17 out of 20 questions correct on her vocabulary quiz. What percent of the questions did she get right?
To find the percentage of questions Claire got right, you can divide the number of questions she got right by the total number of questions and multiply by 100.
In this case, Claire got 17 questions right out of a total of 20 questions.
17 / 20 = 0.85
To convert this decimal to a percentage, multiply by 100:
0.85 * 100 = 85
So, Claire got 85% of the questions right.

Solve this problem.
Of 3,000 pet owners surveyed, 15% adopted their pets from an animal shelter. How many pets were adopted from the shelter?
To find the number of pets that were adopted from the shelter, you can multiply the total number of pet owners by the percentage that adopted their pets from an animal shelter.
In this case, we have 3,000 pet owners and 15% adopted their pets from an animal shelter.
To calculate the number of pets adopted from the shelter:
Number of pets adopted = Total number of pet owners * Percentage of pet owners who adopted
Number of pets adopted = 3,000 * 0.15
Number of pets adopted = 450
Therefore, 450 pets were adopted from the animal shelter.

Solve this problem.
Of 3,000 pet owners surveyed, 9% purchased their pets from a pet store. How many pets were purchased from a pet store?
To find the number of pets that were purchased from a pet store, you can multiply the total number of pet owners by the percentage that purchased their pets from a pet store.
In this case, we have 3,000 pet owners and 9% purchased their pets from a pet store.
To calculate the number of pets purchased from a pet store:
Number of pets purchased = Total number of pet owners * Percentage of pet owners who purchased
Number of pets purchased = 3,000 * 0.09
Number of pets purchased = 270
Therefore, 270 pets were purchased from a pet store.
Question 6 options:
Find the percent of the number.
35% of 120
To find the percent of a number, you can multiply the number by the percentage expressed as a decimal.
In this case, we want to find 35% of 120.
To calculate this, multiply 120 by 0.35:
120 * 0.35 = 42
Therefore, 35% of 120 is equal to 42.

The Lady Eagles won 70% of their 30 basketball games this season. How many games did they win?
To find the number of games the Lady Eagles won, you can multiply the total number of games by the percentage they won.
In this case, the Lady Eagles won 70% of their 30 basketball games.
To calculate the number of games they won:
Number of games won = Total number of games * Percentage of games won
Number of games won = 30 * 0.70
Number of games won = 21
Therefore, the Lady Eagles won 21 games this season.
Solve this problem. To maintain a healthy diet, no more than 30% of calories consumed each day should come from fat. A normal, healthy teenage girl needs about 2,000 calories each day. How many calories should come from sources other than fat in a teenage girl's diet each day?
To find how many calories should come from sources other than fat in a teenage girl's diet each day, you need to calculate 30% of the total calorie intake.
The total calorie intake is 2,000 calories per day.
To calculate the calories from fat, you can multiply 2,000 by 30% expressed as a decimal:
2,000 * 0.30 = 600
Therefore, 600 calories should come from fat in a teenage girl's diet each day.
To find the calories from sources other than fat, subtract the calories from fat from the total calorie intake:
2,000 - 600 = 1,400
Therefore, 1,400 calories should come from sources other than fat in a teenage girl's diet each day.
Question 9 options:
Solve this problem.
An appropriate tip for a waiter at a restaurant is at least 15%. If a meal cost $20, how much money should be left for the tip?
To calculate the amount of money that should be left for the tip, you can multiply the cost of the meal by the tip percentage.
In this case, the meal cost is $20 and the tip percentage is 15%.
To calculate the tip amount:
Tip amount = Cost of the meal * Tip percentage
Tip amount = $20 * 0.15
Tip amount = $3
Therefore, $3 should be left for the tip.

Select the correct answer.
Question 10 options:
fraction numerator 4 over denominator 5 end fraction
fraction numerator 8 over denominator 25 end fraction
16 over 25
fraction numerator 2 over denominator 3 end fraction
To change 64% to a fraction, we divide the percentage by 100 and simplify if possible.
The given percent is 64%.
We can write this as 64/100.
To simplify this fraction, we divide both the numerator and denominator by their greatest common divisor, which is 4 in this case.
64/100 simplifies to 16/25.
So, the correct answer is 16/25.

Since the spinner is divided into six equal segments numbered one through six, we have a total of six possible outcomes.
To find the probability of landing on the number 4, we need to determine how many favorable outcomes there are (landing on 4) out of the total number of possible outcomes (6).
In this case, there is only one favorable outcome (landing on 4), and there are six total possible outcomes.
So, the probability of landing on 4 is 1/6.

To find the probability of selecting a consonant from the word SURPRISE, we need to determine the number of consonants in the word and divide it by the total number of possible letters to choose from.
In the word SURPRISE, there are 5 consonants: S, R, P, R, and S.
There are a total of 8 letters in the word.
So, the probability of choosing a consonant is 5/8.

To find the probability that the first scientist will be assigned to monitor either the creepmeter or the laser reflector, we need to determine the number of favorable outcomes (in this case, the number of devices that are either the creepmeter or the laser reflector) out of the total number of possible outcomes.
There are a total of 7 different devices, so there are 7 total possible outcomes.
To determine the number of favorable outcomes, we need to count the number of devices that are either the creepmeter or the laser reflector. Let's assume that there are 2 devices that fit this criteria.
Therefore, the number of favorable outcomes is 2.
So, the probability that the first scientist will be assigned to monitor either the creepmeter or the laser reflector is 2/7.

To find the probability of landing on a number greater than 3, we need to determine the number of favorable outcomes (numbers greater than 3) out of the total number of possible outcomes.
In this case, the spinner is divided into six equal segments numbered one through six.
Numbers greater than 3 would be 4, 5, and 6, which is a total of three favorable outcomes.
Therefore, the probability of landing on a number greater than 3 is 3/6, which simplifies to 1/2.
