A piece of string is 5 5/8 inches long. How much should Lena cut off to make it 3 1/2 inches long?

Respuesta :

Answer:

2 1/8 inches

Step-by-step explanation:

First, we make the fractions into improper fractions:

5 5/8 = 45/8

3 1/2 = 7/2

Now we make them to have the same denominator

7/2 = 28/8

Now we substract

45/8 - 28/8 = 17/8

17/8 =  2  1/8 inches

= 2+5/8-1/2
