Question

How do you convert `2 1/5` into a decimal and a percent?

Answer 1

`2 1/5=2.20=220%`

Explanation:

As `1/5=(1×20)/(5×20)=20/100`,

we can write `2 1/5` as `2 20/100` or `2.20` in decimal form.

To write a number in percents, just multiply by `100` and add sign `%` to it.

Therefore `2 1/5=2.20=2.20×100%=220%`.
