Brianna has 6 bags of soil. Filling one flowerpot requires
1
3
of a bag of soil. How many flowerpots can be filled with these 6 bags?
To find the number of flowerpots that can be filled, we need to divide the total amount of soil by the amount needed for one flowerpot.
First, we need to convert the fraction 1/3 to a decimal by dividing 1 by 3:
1 ÷ 3 = 0.3333 (rounded to four decimal places)
Now we can divide the total amount of soil (6 bags) by the amount needed for one flowerpot (0.3333 bags):
6 ÷ 0.3333 ≈ 18
Therefore, Brianna can fill about 18 flowerpots with the 6 bags of soil.
How many
1
5
s are in 9?
To find out how many 1/5s are in 9, we need to divide 9 by 1/5:
9 ÷ 1/5
To divide by a fraction, we can multiply by its reciprocal:
9 ÷ 1/5 = 9 × 5/1 = 45
Therefore, there are 45 1/5s in 9.
Devon has 3 gallons of water in a large container. He begins to fill up glasses that each hold
1
8
gallon of water. How many glasses can he fill up until the water runs out?
To find out how many glasses of water Devon can fill up, we need to divide the total amount of water in gallons by the amount of water in each glass in gallons:
3 ÷ 1/8
To divide by a fraction, we can multiply by its reciprocal:
3 ÷ 1/8 = 3 × 8/1 = 24
Therefore, Devon can fill up 24 glasses of water until the water runs out.
The following question has two parts. First, answer part A. Then, answer part B.
Part A
"If you share 7 apples equally with 3 people, then there are
2
1
3
..."
First, complete the sentence. Then, briefly explain what the whole number 2, the denominator 3, and the numerator 1 mean in this problem.
Part A answer:
"If you share 7 apples equally with 3 people, then there are 2 whole apples and 1/3 of an apple for each person."
Explanation:
The whole number 2 represents the number of whole apples that can be shared equally among the three people (i.e., each person gets 2 whole apples). The numerator 1 represents the additional number of apples that needs to be shared equally among the three people, but since it's less than one whole apple, it is expressed as a fraction. The denominator 3 represents the total number of people sharing the 7 apples. Therefore, 2 whole apples and 1/3 of an apple is the amount that each person gets when 7 apples are shared equally among 3 people.
