Question

What is 7 2/3 - 3 7/8 =

Answer 1

We are being asked to subtract two mixed numbers, 7 2/3 - 3 7/8,

First, we need to convert the mixed numbers to improper fractions:

`7(2)/(3)-3(7)/(8)=(21+2)/(3)-(24+7)/(8)=(23)/(3)-(31)/(8)`

Until now, we have changed to improper fractions, now we can make the difference:

`(23)/(3)-(31)/(8)=((23\cdot8)-(3\cdot31))/(24)=(184-93)/(24)=(91)/(24)`
