5.4 turned into a percent would be 540%
"Percent" means "per 100" or "over 100". So, to convert 5.4 to a percent, we rewrite 5.4 in terms of "per 100" or over 100.
Multiply 5.4 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.
[tex]\frac{5.4}{1}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{540}{100}[/tex]
540/100 is 540 over 100 and means 540 per 100. 540 "per 100" means 540 "percent" or 540%
Therefore, we have shown that
5.4 = . 540%
