Question

the sum of two national numbers 6/7 . if one of the them is 1/3, find the other. 3 ​

Answer 1

Answer:

the other rational number is 11/21

Step-by-step explanation:

let the other rational number be: X

1/3 + X = 6/7

X= 6/7 - 1/3 ( the sign changes as we move it to the other side)

LCM of 7 & 3 : 21

X = 18/21 - 7/21

X = 11/21
