Answer 1

$7\frac{7}{12}+(3\frac{1}{2}+1\frac{7}{8})=$
$=\frac{91}{12}+(\frac{28}{8}+\frac{15}{8})=$
$=\frac{91}{12}+\frac{43}{8}=\frac{162+129}{24}=$
$=\frac{291}{24}=12\frac{3}{24}=12\frac{1}{8}$

Answer 2

Answer:

24.0416 with a line above the 6

Step-by-step explanation:

First you use PEMDAS

31/2= 15.5

17/8=2.125

so 15.5 + 2.125 = 17.625

so the problem now is 77/12 + (17.625)

Son 77/12= is 6.416

so now you add

6.416 + 17.625= 24.0416

hope this helps
