Question

Find the sum....
3/2 + 4/5 &
12/5 + 6/7​

Answer 1

Answer:

5.843

Step-by-step explanation:

3/2 + 4/5

taking LCM of 2 and 5 as 10

=(3 x 5)/(2 x 5) + (4 x 2)/( 5 x 2)

=15/10 +8/10

=(15+8)/10

=23/10

=2.3

12/5 + 6/7​

taking LCM of 5 and 7 as 35

=(12 x 7)/(5 x 7) + (6 x 5)/(7 x 5)

=84/35 + 30/35

=(84+30)/35

=124/35

=3.5428

=3.543

therefore the sum of 3/2 + 4/5 & 12/5 + 6/7​

=2.3 + 3.543

=5.843

3*35/2*35 + 4*14/5*14 + 12*14/5*14 + 6*10/7*10

105/70 + 56/70 + 168/70 +60/70

389/70
