How much brown sugar will be needed if this recipe is tripled?
Underline Starts Chocolate Chip Cookies Underline Ends
2 c flour
1 c butter
1 c brown sugar
2 eggs
12 oz choc. chips
Makes 2 dozen cookies.
Select the correct answer.
Question 2 options:
3 cups
1 cup
4 cups
To determine how much brown sugar will be needed if the recipe is tripled, we need to multiply the original amount of brown sugar (1 cup) by 3.
1 cup x 3 = 3 cups
Therefore, the correct answer is 3 cups.

To express the ratio 12 to 36 in simplest fraction form, we need to find the greatest common divisor (GCD) of the two numbers and divide both numbers by it.
The GCD of 12 and 36 is 12. So, by dividing both numbers by 12, we get:
12 ÷ 12 = 1
36 ÷ 12 = 3
Therefore, the ratio 12 to 36 in simplest fraction form is 1/3.
The correct answer is:
1/3

Certain companies that produce popcorn develop a criteria for what makes a good popcorn kernel. Write a ratio in simplest form that compares the number of good kernels to the number of bad kernels if 300 kernels are examined and only 200 are accepted.
Type the correct answer in reduced form.
Blank Space__________
To find the ratio of good kernels to bad kernels, we need to determine the number of each. Given that 200 kernels are accepted out of 300 examined, the remaining 100 kernels are considered bad.
The ratio of good kernels to bad kernels is 200:100. Simplifying this ratio by dividing both numbers by their greatest common divisor (GCD), which is 100, we get:
200 ÷ 100 = 2
100 ÷ 100 = 1
Therefore, the ratio of good kernels to bad kernels in simplest form is 2:1.
The correct answer is:
2:1
What is the unit rate in this problem?
12 cars passed the station in 6 minutes.
Blank Space__________cars per hour
To find the unit rate, we need to determine the rate of cars per hour.
In 6 minutes, 12 cars passed the station. To find the rate per hour, we need to scale this up.
There are 60 minutes in an hour, so we can set up a proportion:
6 minutes is to 12 cars as 60 minutes is to x cars.
Using cross-multiplication, we find:
6 * x = 12 * 60
6x = 720
x = 720/6
x = 120
Therefore, the unit rate is 120 cars per hour.
The correct answer is:
120 cars per hour.

If a softball player gets 2 hits in 5 times at bat, how many hits should she expect out of 20 times at bat?
Blank Space__________hits
To solve this problem, we can set up a proportion to find the expected number of hits when the player is at bat 20 times.
If the player gets 2 hits in 5 times at bat, we have the ratio 2:5.
We can set up the proportion:
2 hits is to 5 times at bat as x hits is to 20 times at bat.
Using cross-multiplication, we find:
5 * x = 2 * 20
5x = 40
x = 40/5
x = 8
Therefore, the player should expect to get 8 hits out of 20 times at bat.
The correct answer is:
8 hits.
