Question

How do you simplify `2/15 - 1/10`?

Answer 1

See a solution process below:

Explanation:

First, multiply each fraction by the appropriate form of `1` to put the fractions over a common denominator without changing the value of the fractions:

`(2/2 xx 2/15) - (3/3 xx 1/10) =>`

`(2 xx 2)/(2 xx 15) - (3 xx 1)/(3 xx 10) =>`

`4/30 - 3/30`

Now, subtract the numerators over the common denominator:

`4/30 - 3/30 =>`

`(4 - 3)/30 =>`

`1/30`
