Question

what should be added to 3/7 to get 8/-3​

Answer 1

Answer:

let the added number be x

according to question

3/7+x = 8/-3

x = 8/-3 – 3/7

x = -(8×7)–(3×3)/21

x = -56-9/21

x = -65/21

Answer 2

Answer:

-65/21 should be added to 3/7 to get 8/-3

Step-by-step explanation:

let the number to be added be x

3/7 + x = 8/-3

x = -8/3 - 3/7

LCM of 3 and 7 is 21

x = -56/21 - 9/21

x = -56 - 9 / 21

x = -65 / 21
