Question

How do you subtract `\frac { 22} { 7} - \frac { 2} { 3}`?

Answer 1

`52/21`

Explanation:

first get a common denominator. since the 2 denominators are 3 and 7, the common factor is 21. so multiply the first fraction by 3 and the second fraction by 7 to get the common denominator.

`3*(22/7)` - `7*(2/3)`

or this can also be written as:

`(3*22-2*7)/(7*3)`

this will give us:

`(66-14)/21`

so the answer will be:

`52/21`
