Answer 2

Hey Cool Readers,

LCM is used when we want to add or subtract.

It is basically the Lowest Common Multiple of both the numbers (here 5 and 7).

To find we can use ladder method or for small numbers we can directly find by multiplying these two numbers (LCM=35=7×5)

Sum will be,

28/35+30/35
28+30/35
58/35
