Question

Which three fractions below has the sum that is a whole number?9/12, 1/2, 3/8, 6/10, 8/15, 3/4

Answer 1

Answer::

`(9)/(12),(1)/(2),and\text{ }(3)/(4)`

Explanation:

Given the fractions:

`(9)/(12),(1)/(2),(3)/(8),(6)/(10),(8)/(15),(3)/(4)`

Reduce each of the fractions to their lowest form.

`(3)/(4),(1)/(2),(3)/(8),(3)/(5),(8)/(15),(3)/(4)`

On observation:

`(3)/(4)+(1)/(2)+(3)/(4)=(3+2+3)/(4)=(8)/(4)=2`

Therefore, the three fractions whose sum is a whole number are:

`(9)/(12),(1)/(2),and\text{ }(3)/(4)`
