Melissa is making clothes for her dolls. She has 7/8 yard of fabric. Each doll shirt requires 2/7 of a yard of fabric. How many whole shirts can she make for her dolls? a. 2 b. 3 c. 4 d. 5

Answers

Step-by-step explanation:

Since you have 7/8 of a yard of fabric and 2/7 needed you would take the 7/8 and divide by 2/7

7/8 / 2/7

Since these are fractions you would take the second number and turn in into its reciprocal

7/8 x 7/2

49/16

3 1/16

You can make 3 full shirts

A topical cream is sold in a 34-gram container. The average amount of topical cream used per application is 2\7 grams. How many applications can be made with the container?

Answers

Since an application is 2/7 grams.

Number of applications = 34 ÷ 2/7

= 34 × 7/2

= 17 × 7

= 119

Number of applications = 119

Final answer:

This is a division problem. You find the number of applications by dividing the total weight of the cream (34 grams) by the amount used per application (2/7 grams), which gives us 119 applications.

Explanation:

This is a problem of simple division under the topic of arithmetic in mathematics. You are given a total quantity of topical cream (34 grams) and you know how much is used per application (2/7 grams). So, the number of applications can be found by dividing the total quantity by the amount used per application.

To calculate, divide 34 (the total weight of the cream) by 2/7 (the amount used per application).

This gives us, 34 ÷ (2/7) = 119,

Therefore, you can make 119 applications with the container of cream.
