Question

How do you evaluate `\frac { 5} { 6} \times \frac { 80} { 1}`?

Answer 1

Multiply the numerators Multiply the denominators and divide out any common factors.

Explanation:

`5/6 xx 80/1 = (5 xx 2 xx cancel2 xx 2 xx 2 xx 5)/ (cancel2 xx 3)`

`2/2 = 1` so one set of 2s divides out leaving

`(5 xx 2 xx 2 xx 2 xx 5) /( 3)` This gives

`200/3 = 66 2/3`
