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

Explanation:

7/8 = 49/56 after multiplying top and bottom by 7

2/7 = 16/56 after multiplying top and bottom  by 8

Both fractions involve 56 as the denominator. So we can think of "56ths" as a unit. She has 49 units of fabric and each shirt requires 16 units.

49/16 = (48+1)/16 = 48/16 + 1/16 = 3 + 1/16

She can make 3 full shirts, and then the 1/16 is the leftover bit which we ignore.

3 whole shirts

Step-by-step explanation:

(7/8) / (2/7) = 7/8 * 7/2 = 49/16 = 3 1/16 so, 3 whole shirts { (7/8 divided by (2/7 = 7/8 x 7/2 = 49/16 or 3 1/16 so, 3 whole shirts in total. }

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

it has changed from the width and the height.
