Question

Rename 1/5 and 9/10 using the least common denominator.

Answer 1

`(2)/(10)` and
`(9)/(10)`

Explanation:

First, llook at the denomintor. Do 5 and 10 have something in common? 5x2=10 and 10x1=10. The common denominator is 10. Then you mulitply the numerator with what you mulitpierd with the denominator. 9x1=9 and 10x1=10 =
`(9)/(10)`. 1x2=2 and 5x2=10 =
`(2)/(10)`. So, It is
`(2)/(10)` and
`(9)/(10)`.
