420%

In order to convert a number to a percent, multiply it by 100

#4.2*100=420%#

#420%#

Remember than #4.2# can be written with two decimal places as #4.20#

The second decimal place represents hundredths.

Therefore #4.2# actually means #420/100#

A percent is an amount out of #100#

This is already out of #00#, so it is a percent.

#4.2 = 4.20 = 420/100 = 420%#
