Answer 2

Answer:

6/7 + 3/4

In this question, the denominators are not same. So, we have to make the denominators same by finding the LCM of the denominators.

So, the LCM of 7 and 4 = 28

Now, by what we should multiply the number with to get 28 as the denominator.

⇒ 6 x 4 / 7 x 4    +     3 x 7 / 4 x 7

⇒ 24/28 + 21/28

Now that the denominators are same, we can add the fractions.

⇒ 24/28 + 21/28

⇒ 25/28

∴ The sum of 6/7 and 3/4 is 25/28
