Question

How do you write 4.20 as a fraction?

Answer 1

`4.20=color(blue)(21/5)=color(magenta)(4 1/5)`

Explanation:

`4.20`
`color(white)("XXX")=(4.20)/1`

`color(white)("XXX")=420/100`

`color(white)("XXX")=42/10`

`color(white)("XXX")=21/5` (as an "improper fraction")
or
`color(white)("XXX")=4 1/5` (as a "mixed fraction")
