Answer 1

Answer:

3

Step-by-step explanation:

Basically, find the LCM of denominators.

Like,

4/5 + 3/7

LCM = 35 (as 5,7 are prime numbers)

so 4/5's denominator is 5

so 5* _ = 35

35/5 = 7

now, multiply denominator and numerator with 7

4/5 = 28/35

you can see these are equivalent

in the same way, 3/7 = 15/35

so now add them, u get 43/35

this was an example

in the same way, do for the question u asked
