Answer:

4 19/20

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]=8+\frac{7}{10}=3-\frac{3}{4}[/tex]

Solving the whole number parts

[tex]8-3=5[/tex]

Solving the fraction parts

[tex]\frac{7}{10}-\frac{3}{4}=[?][/tex]

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

LCD = 20

[tex]\frac{14}{20}-\frac{15}{20}=-\frac{1}{20}[/tex]

Combining the whole and fraction parts

[tex]5-\frac{1}{20}=4\frac{19}{20}[/tex]
