Answer :

To do it without a calculator you would first want to get the denominator to be 100. 
To do this you would have to multiply both the top and bottom by 4
So now you have 72/100. You would then divide 72 by 100. To do this you simply move the decimal left two place, and you would get .72

In order to write [tex]\frac{18}{25}[/tex] as a decimal, we need to find a fraction equivalent to [tex]\frac{18}{25}[/tex] with 100 in the denominator. We can multiply the numerator and the denominator of [tex]\frac{18}{25}[/tex] by 4 and we will get the equivalent fraction [tex]\frac{72}{100}[/tex]. Remember that the hundredths place is two places to the right of the decimal point so we can write [tex]\frac{72}{100}[/tex] as 0.72

Therefore, 18/25 is equivalent to 0.72.
