Please help me with this question I’m doing points

Answer 1

The first option
`(17)/(21)`

Explanation:

In order to solve this question we have to add the three fractions. In order to add the fraction we need them to have the least common dinoinator. For 3, 7, and 21 it is 21. So...

`(2)/(3) - (4)/(7) + (15)/(21) = (14)/(21) - (12)/(21) + (15)/(21) = (17)/(21)`

Answer 2

the answer is simply 17/24
