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.
