Find the sum of 8/13 and 3/11
Solution:
Given, the numbers are 8/13 and 3/11
We have to find the sum of the numbers.
Sum = 8/13 + 3/11
Taking LCM,
LCM of 13 and 11 = 13 × 11 = 143
Now, 8/13 = 8 × 11 / 13 × 11 = 88/143
3/11 = 3 × 13 / 11 × 13 = 39/143
8/13 + 3/11 = 88/143 + 39/143
Since the numbers have same denominator, we get
= (88 + 39)/143
= 127/143
Therefore, the sum is 127/143
