Answer 1

The answer is eight and nine-tenths

Explanation:

Eliminating a negative and changing our operation.

=−4 1/5+13 1/10

Rewriting our equation with parts separated

=−4−15+13+110

Solving the whole number parts

−4+13=9

Solving the fraction parts

−1/5+1/10=?

Find the LCD of 1/5 and 1/10 and rewrite to solve with the equivalent fractions.

LCD = 10

−2/10+1/10=−110

Combining the whole and fraction parts

9−1/10=8 9/10
