George lynn and crosby meet at the playground george lives 5/6 mile from the play ground. lynn lives 4/6 mile from the play ground. crosby lives 7/8 mile from the play ground. who lives the closest to the playground

We need to compare the fractions:  4/6  5/6  and 7/8

And find the smallest.

By comparing 4/6 and 5/6 we know that 4/6 is smaller, because since they both have same denominator, the smaller number would be the smaller.

And of course 4/6 can not be bigger than 7/8.  7/8 is  a lot bigger.

So 4/6 is the smallest.  Therefore Lynn that lives 4/6 mile from the play ground lives the closest from the play ground.
