Question

the sum of two rational us -4/7.if one of the number is -2/3,find the other number​

Answer 1

Answer:

other rational no. is 2/21

Step-by-step explanation:

let the other no. be x

x + (-2/3) = -4/7

x - 2/3     = -4/7     ( +- = -)

x = -4/7 + 2/3

x = (-4/7)X3 + (2/3)X7  (LCM)

x = -12/21  +  14/21

x = 2/21
