Question

Graham is hiking a trail that is 5 1/2 miles long. He has hiked 3 5/8 miles so far. How many miles does he have left to hike?

Answer 1

`1(7)/(8)`

Explanation:

In order to find the answer to this question you must convert the mixed numbers into improper fractions and then subtract.

`5(1)/(2) -3(5)/(8)`

Convert into improper fractions

`5(1)/(2) =2*5+1=(11)/(2)`

`3(5)/(8) =8*3+5=(29)/(8)`

Now subtract by finding the common denominator:

`(11)/(2) * 4 = (44)/(8)`

`(29)/(8) *1=(29)/(8)`

`44 -29=15`

`=(15)/(8) /1(7)/(8)`

Hope this helps.
