Question

The sum of three mixed numbers is `28\frac { 19} { 20}`. Two of the numbers are `9 1/2` and `9 3/4`. What is the third number?

Answer 1

`x=9 7/10`

Explanation:

Let the third number be `x`

SO `9 1/2 +9 3/4 + x = 28 19/20`

`x=28 19/20-9 1/2-9 3/4` (put these numbers into a calculator)

`x=9 7/10`
