I need help with this problem please.

Question

Trina is making quilts for sewing class. She will use 21 yards of yellow fabric, 11.2 yards of green fabric, and 24.3 yards of blue fabric. This amount makes 25 quilts. How many yards are used for each quilt?

Answer 1

Hello!

Since this is a word problem we need to identify the important information. What do we know?

1. 21 yards of yellow
2. 11.2 yards of green
3. 24.3 years of blue
4. That makes 25 quilts

So think about how we would answer this question. How many yards in each quilt? We divide right?

Total Yards

---------------- = Yards Per Quilt

Total Quilts

Think of the line between the numerator (top number) and the denominator as the word "per". To find the total number of yards per quilt we divide Total Yards by Total Quilts.

Do we know the top & bottom numbers? Yep. Total yards is:

21 yellow + 11.2 green + 24.3 blue = 56 yards

Do we know the bottom number? Of course, they told us it is 25.

So,

Total Yards 56.5

------------------ = ------ = 2.25 yards per quilt

Total Quilts 25

Hope that helps!
