Question

what is the fraction of 3/4 + 4/5​

Answer 1

Answer:

31/20 is the answer

Step-by-step explanation:

3/4 + 4/5

= 3×5/4 + 4×4/5

= 15+16/4×5

= 31/20

Answer 2

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

=

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

(Because L.C.M is 20)

=

$\frac{15 + 16}{20}$

=

$\frac{31}{20}$
