Question

Sum of three like fractions is 18/11. the first 2 fractions are 1/11 and 9/11. find the third fraction.

Answer 1

Answer:

$\frac{8}{11}$

Step-by-step explanation:

Since the fractions are like, their denominators are 11, then

consider the values that sum to give 18 , that is

1 + 9 + ? = 18

10 + ? = 18 ( subtract 10 from both sides )

? = 8

Then the third fraction is $\frac{8}{11}$
