Question

what should be added to -4/5 to get -3/8 ?​

Answer 1

➤ Answer :-

$\dashrightarrow \sf \frac{( - 4)}{5} + (x) = \frac{( - 3)}{8}$

$\dashrightarrow \sf (x) = \frac{( - 3)}{8} - \frac{( -4)}{5}$

LCM of 8 and 5 is 40.

$\dashrightarrow \sf \frac{( - 3) \times 5}{8 \times 5} - \frac{( - 4) \times 8}{5 \times 8}$

$\dashrightarrow \sf \frac{( - 15)}{40} - \frac{( - 32)}{40} = \frac{( - 15) - ( - 32)}{40}$

$\dashrightarrow \sf \frac{17}{40}$

$\Huge\therefore$$\sf\frac{17}{40}$ should be added to $\sf\frac{-4}{5}$ to get $\sf\frac{-3}{8}$
