Answer 1

4 19/20

Explanation:

Rewriting our equation with parts separated

`=8+(7)/(10)=3-(3)/(4)`

Solving the whole number parts

`8-3=5`

Solving the fraction parts

`(7)/(10)-(3)/(4)=[?]`

Find the LCD of 7/10 and 3/4 and rewrite to solve with the equivalent fractions.

LCD = 20

`(14)/(20)-(15)/(20)=-(1)/(20)`

Combining the whole and fraction parts

`5-(1)/(20)=4(19)/(20)`
