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 23 of that. But how much is 23 of 72? All you have to do is multiply!
7223=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?
7273=21146=76
Here it is, she will have 76 yards of fabricleft. If you want the answer in that notation, it is 116

Step 1
So, Erica bought 312 yards of fabric. o make this easier to work with, we convert it to an improper fraction. Now we know Erica has 72 yards of fabric.
Next, she uses 23 of it. This means that 13(=123) of the fabric is remaining.
To get 13 of 72, we just multiply them:
(13((72)=76
So now we know Erica has 76 yards of fabric remaining. This is equivalent to 116 yards, or 1 yard and 6 inches.
