Answer 1

The answer is:

-0.275

calculation

Answer 2

> $\frac{-9}{4}+\frac{-13}{-12}+\frac{13}{8}+\frac{11}{-15}$ = -0.2747

Explanation:

Given:

-9/4+-13/-12+13/8+11/-15

Solution:

==> Make a bracket to separate the values

==> (-9/4)+(-13/-12)+(13/8)+(11/-15)

==> Solve the brackets separately

==> $\frac{-9}{4}+\frac{-13}{-12}+\frac{13}{8}+\frac{11}{-15}$

==> $\frac{-9}{4}=-2.25$

==> $\frac{13}{12} =1.0833$

==> $\frac{13}{8} =1.625$

==> $\frac{11}{-15}=-0.733$

==> Substitute the values

==> -2.25+1.0833+1.625-0.733

==> -2.25+2.7083-0.733

==>-2.983+2.7083

==> -0.2747

==> $\frac{-9}{4}+\frac{-13}{-12}+\frac{13}{8}+\frac{11}{-15}$ = -0.2747
