Question

-2/3 + 9/20 find the answer​

Answer 1

Question:-

$- \frac{ 2}{3} + \frac{9}{20}$

Solution:-

LCM of 3 and 20 is 60

So,

$- \frac{2}{3} \times \frac{20}{20} = - \frac{40}{60}$

And

$\frac{9}{20} \times \frac{3}{3} = \frac{27}{60}$

$- \frac{2}{3} + \frac{9}{20} = - \frac{40}{60} + \frac{27}{60}$

$= > \frac{ - 40 + 27}{60}$

$= > - \frac{13}{60}$
