Question

Help please! I would greatly appreciate it!

Sarah is making pillows. She uses 2 1/3 yards of fabric to make 5 pillows. How many yards of fabric will Sarah use to make 20 pillows?
A. 6 1/3 yd
B. 9 1/3 yd
C. 17 1/3 yd
D. 42 6/7 yd

P.S. Thanks!

Answer 1

(7/3) / 5 = (7/3) * 1/5 = 7/15 for one pillow.

20 * 7/15 = ?

Answer 2

I'm sorry but that just looks like gibberish to me (she said sheepishly). Can you explain it to me?

Answer 3

2 1/3 = 7/3

Divide 7/3 by 5 to find the amount of material needed for one pillow.

Multiply the amount for one pillow by 20 to find the amount for 20 pillows.

Thank you Ms. Sue!

You're welcome.

Answer 6

Wait... How do you divide 7/3 by 5? I'm so sorry this is all so confusing to me.

Answer 7

7/3 divided by 5/1 = 7/3 x 1/5

Answer 8

Here's one of my little secrets.

I often double check my work with fractions by converting to decimals and using my simple calculator.

2 1/3 = 2.33

2.33 / 5 = 0.466

0.466 * 20 = 9.32 = 9 1/3
