Question

the sum of two fractions is 7 by 9. if one of the fractions is 1 by 3, find the other?​

Answer 1

Answer:

4/9

Step-by-step explanation:

Let the fractions be a/b and x/y

given a/b = 1/3

x/y = ?

sum of fractions = 7/9

we know,

x/y + a/b = 7/9

or, x/y + 1/3 = 7/9

or, x/y = 7/9 - 1/3

or, x/y = 7-3/9(by taking LCM of 3 and 9)

or, x/y = 4/9

therefore, the other fraction is 4/9
