I have to answer the follwoing question:
Jades mother was making curtains for the dining room. She use 37 3/4 yards of fabric for the curtain panels. 13 2/7 yards of fabric for the valance. and 6ft 2in. of cord for the tiebacks. HOW many yards of fabric did she use to make the curatins and valance?
i got a ttl of 57 1/28 yards
37 3/4 = 37 21/28
+ 13 2/7 = 13 8/28
ttl: 50 29/28 = 1 1/28
= ttl: 51 1/28 yards
is this right??
You're right.
Your calculation is almost correct, but there is a small error in your addition. Let's break it down step by step:
First, convert the mixed numbers into improper fractions:
37 3/4 = (37 * 4 + 3)/4 = 149/4
13 2/7 = (13 * 7 + 2)/7 = 93/7
Next, find the common denominator for the fractions:
The denominators are 4 and 7, so the common denominator is 4 * 7 = 28.
Now, convert the fractions to have a common denominator of 28:
37 3/4 = (149/4) * (7/7) = 1043/28
13 2/7 = (93/7) * (4/4) = 372/28
Now, add the fractions together:
1043/28 + 372/28 = 1415/28
Finally, simplify the fraction:
1415/28 = 50 15/28
So, the correct answer is 50 15/28 yards.
