Answer 2

Answer:

Question :-

Solve these (a) 4/5+9/-18

Required Answer :-

$\frac{- 27}{ - 90}$

Solution :-

$\frac{4}{5} + \frac{9}{ - 18}$

$=\frac{4 \times - 18}{5 \times - 18} + \frac{9 \times 5}{- 18 \times 5}$

$=\frac{ - 72 }{ - 90} + \frac{45}{ - 90}$

$=\frac{ - 72 + 45}{ - 90}$

$=\frac{ - 27}{ - 90}$

So your answer is -27/-90
