Pia sewed 7 skirts. each skirt used 2/5 yard of fabric. how much fabric did pia used altogether

To solve this, we need to multiply 7 and 2/5.

7 = 7/1

2/5 = 2/5

7 x 2 = 14

1 x 5 = 5

= 14/5

Simplifying 14/5 . . .

14/5 = 2 4/5

Pia used 2 4/5 yards of fabric.

I hope this helped! :)

Pia sewed 7 skirts. She needed yards of fabric for each skirt. To find the total amount of fabric she used, multiply the amount for 1 by how many she sewed in all.

That means you have to multiply by 7

She used a total of yards of fabric

Hope this helps! :)

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
