Question

Vanessa has 3 yards of cotton. She needs 2/5 yard for each skirt she makes. How many skirts can she make? What does the fractional part of the answer mean?

a) 1.2 skirts; the fractional part represents the remaining fabric.
b) 7.5 skirts; the fractional part indicates excess fabric.
c) 2.5 skirts; the fractional part represents the remaining fabric.
d) 1.5 skirts; the fractional part indicates excess fabric.

Answer 1

Vanessa can make 7 full skirts with 3 yards of cotton, given that she requires 2/5 yard of cotton per skirt. The fractional part, 0.5, represents half of the 2/5 yard of cotton that would be needed to make another skirt, indicating excess fabric.

Step-by-step explanation:

The question asks how many skirts Vanessa can make with 3 yards of cotton when she needs 2/5 yard for each skirt. To find the number of skirts Vanessa can make, we divide the total yards of fabric by the yardage needed for one skirt: 3 yards ÷ (2/5) yards/skirt = 3 ÷ (2/5) = 3 ÷ 2 ÷ 5 = 15/2 = 7.5 skirts. So Vanessa can make 7 full skirts, and the fractional part indicates the amount of fabric she will have left over after making 7 skirts. In other words, Vanessa will have half of the 2/5 yard needed for another skirt left over.
