The sum of two rational numbers is 4/7.If one of them is 3/14 find another numbers.

5/14

Step-by-step explanation:

let the aaded no be x

3/14 + x = 4/7

x = 4/7-(3/14)

x = 5/14

here added no is 5/14

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

i just took the test, the correct answer is .. 31.5 in.
