Answer 2

$\frac{3}{4} - ( - \frac{4}{5} ) \: is \: not \: equal \: to:$

You can write any wrong answer here in this question.

$\frac{3}{4} - ( - \frac{4}{5} ) \: is \: equal \: to:$

But here you have to write the correct answer

Steps of the correct answer:

$= \frac{3}{4} - ( - \frac{4}{5} )$

$= \frac{3}{4} + \frac{4}{5}$

LCM of 4 and 5 = 20

$= \frac{(3 \times 5) + (4 \times 4)}{20}$

$= \frac{15 \times 16}{20}$

$= \frac{31}{20}$

$= 1\frac{11}{2}$

This is the correct answer of this question.
