Question

3/8 + (-4/5) + (-3/8 ) + 5/4

Answer 1

Rearrange:
$\frac{3}{8}$-$\frac{3}{8}$+$\frac{5}{4}$-$\frac{4}{5}$
0+$\frac{5}{4}$-$\frac{4}{5}$
We need the same denominator in order to subtract
$\frac{5}{4}$×($\frac{5}{5}$) - $\frac{4}{5}$×($\frac{4}{4}$)
$\frac{25}{20}$-$\frac{16}{20}$
$\frac{9}{20}$
Final Answer: $\frac{9}{20}$
