Question

A tailor cuts 2 3/4 yards from a roll of fabric to make one curtain.

Answer 1

Answer:

You know, I really don’t like the 312 notation, I think it’s a lot more confusing than writing 3.5 or even 72. I’ll use the latter here, to make the math easier.

Okay, Erica started with 72 yards of fabric. Then, she uses 2/3 of that. But how much is 23 of 72? All you have to do is multiply!

72⋅23=146=73

Alright, she used 73 yards of fabric in the curtain, if you take that out of the total how much will be left?

72−73=21−146=76

Here it is, she will have 76 yards of fabric left. If you want the answer in that notation, it is 116.
