What should we added to -7/3to get 3/7

Answer»

Answer:

58/21

Step-by-step EXPLANATION:

it's ADDITION so we have to make the denominator same, the LCM ( Lowest Common Multiple ) of 3&7 is 21. so both the denominators should be same

-7/3 × 7/7 = -49/21 , 3/7 × 3/3 = 9/21

so the answer will be the difference between (-49/21) and 9/21

so, 9/21 - (-49/21)

= 9 - (-49) / 21

= 9 + 49 / 21

= 58 / 21

so we should add 58/21 to -7/3 to get 3/7
