Mark lives 7/8 mile from school.Claudia lives 3/10 mile from school. How much closer, in miles, does Claudia live to school than Mark? ​

Respuesta :

The first step is to find a common denominator. I'm going to use 80.

So...

7/8 x 10/10=70/80 (Mark)

And...

3/10 x 8/8=24/80 (Claudia)

70/80 - 24/80 = 56/80
