Answer:
1k or k
Step-by-step explanation:
Lets solve the problem without k. The problem would be -6+7. The answer is 1. Then we add the k at the end.
We get 1k, which can be written as just k.
So we have 2 large windows, each needing 3 3/4 yds of fabric....and 3 small windows, each needing 1 1/3 yds of fabric
2(3 3/4) + 3(1 1/3) =
2(15/4) + 3(4/3) =
30/4 + 12/3 =
7 1/2 + 4 =
11 1/2 (or 11.5) yds of fabric are needed <==
