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??
Yes, it's right.
Mrs Sue can you check is this right??
Your calculation is almost correct, but there is a small error in adding the fractions. Let's go through the calculation step by step to ensure accuracy.
First, convert the mixed number to an improper fraction for easier calculation:
37 3/4 = (4 * 37 + 3) / 4 = 149/4
Next, add the fractions:
149/4 + 13 2/7
To add fractions, we need to find a common denominator. The least common multiple (LCM) of 4 and 7 is 28.
Converting fractions to have the same denominator:
149/4 = (149/4) * (7/7) = 1043/28
2/7 = (2/7) * (4/4) = 8/28
Now we can add the fractions:
1043/28 + 8/28 = 1051/28
Next, simplify the fraction:
1051/28 = 37 1/28
So, the total amount of fabric used for the curtains and valance is 37 1/28 yards.
Therefore, your answer should be 37 1/28 yards, not 51 1/28 yards.
