please answer fast​

Answer 1

Answer:

3

Step-by-step explanation:

Remember, to add or subtract a fraction, we first check that the denominator of the fractions are the same.

If not take LCM of the numbers:-

LCM of 7,21,3 = 21

Now make the denominators 21 by multiplying them...

3/7 × 3 = 9/21

6/7 × 3 = 18/21

8/21 will remain as it is.

4/3 × 7 = 28/21

Add the numerators, 9+18+8+28 = 63

The denominator will remain as it is

63/21 = 3
