Answer 2

Given: $\frac{3}{4}+\frac{2}{5} -\frac{5}{20}$

To Find: Simplification

Solution:

L.C.M of 4, 5, 20= 20

∴ $\frac{3}{4}+\frac{2}{5} -\frac{5}{20}$

$= \frac{3\times5+2\times4-5\times1}{20}$

$= \frac{15+8-5}{20}$

$= \frac{18}{20}$

Dividing numerator and denominator by 2, we get,

$=\frac{9}{10}$

Converting it into decimal, we get,

= 0.9

Answer: 0.9
