Answer:

The answer is 7/24

Explanation:

Rewriting our equation with parts separated

=2+16−1−78

Solving the whole number parts

2−1=1

Solving the fraction parts

16−78=?

Find the LCD of 1/6 and 7/8 and rewrite to solve with the equivalent fractions.

LCD = 24

424−2124=−1724

Combining the whole and fraction parts

1−1724=724

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

136−158

Applying the fractions formula for subtraction,

=(13×8)−(15×6)6×8

=104−9048

=1448

Simplifying 14/48, the answer is

=724

Hope I helped :)
