Answer 2

The sum of 2/3, 3/5 and 7/10 is 59/30

Explanation:

Given:

Three numbers 2/3, 3/5 and 7/10

To find:

The sum of the numbers

==> 2/3, 3/5 and 7/10

==> To sum the three numbers , Denominator is different

==> Taking LCM for 3, 5 and 10

LCM of

==> 3 = 3

==> 5 = 5

==> 10 = 5 × 2

The LCM of 3,5 amd 10 is 3 × 2 × 5

The LCM of 3,5 amd 10 is 30

==> 2(10)/3(10)+ 3(6)/5(6) and 7(3)/10(3)

==> 20/30+18/30+21/30

==> Now, The denominator is same

==> So, Add the numerator directly

==> (20+18+21)/30

==> 59/30

The sum of 2/3, 3/5 and 7/10 is 59/30
