Answer 2

To find : sum of rational numbers $\frac{3}{4} + \frac{4}{5} + \frac{8}{25}$

Solution:

• As per given condition we write , $\frac{3}{4} + \frac{4}{5} + \frac{8}{25}$

• To find the sum of given rational numbers we get need to equalize denominators of both the rational numbers. By taking LCM

• Therefore, LCM = $100$

• Now, multiplying numerators of both rational numbers by same number as multiplied by denominators to make LCM.

• Therefore, we get, $\frac{3}{4}+\frac{4}{5}+ \frac{8}{25} =\frac{3 \times 25}{100}+\frac{4 \times 20}{100}+ \frac{8\times 4}{100}$

                                                           $= \frac{75 + 80 + 32 }{100} \\= \frac{187}{100} \\= 1. 87$

Hence, decimal equivalent to $\frac{3}{4} + \frac{4}{5} + \frac{8}{25}$ is $1.87$ .
