Here, cancel the common numbers in LHS and write back the remaining uncancelled numbers to get 4/3 in RHS.

Using same method,

Next, Now in last two questions, we have to do a little differently. Till this much time we did by cancelling the common numbers. So, multiply the numerator and denominator.

So, above question's answer is 3/8.

Likewise, using the same method, find the next question :-

So, next answer is 8/15.

Hope this Helps...
