Question

One blanket requires 2 1/5 feet of fabric. If Mariam wants to make 3 1/2 blankets, how much fabric will she need? (answer in fraction form and SIMPLIFY if possible)

Answer 1

2 1/5 = when you simplify is 11/5
3 1/2= when you simplify is 7/2
Now, if Miriam want to make 3 1/2 blanket you have to multiply for 2 1/5 that is the amount for 1 blanket. And the result it will be how much fabric Miriam will need to make the 3 1/2 blanket
However, you have to
3 1/2 x 2 1/5 = 7 7/10 if you simplify it will be
7/2 x 11/5 = 77/10

Calculation steps:

7/2 x 11/5 = 7 x 11 / 2 x 5 = 77/10 = 7 7/10
So, Miriam will need 7 7/10 feet of fabric to make 3 1/2 blanket.

Hope that help.
