First, convert it to a decimal by dividing it. Then, multiply the decimal by #100%#.

Explanation:

The first step is to change it into a decimal.

#3/20 = 0.15#

You can think of decimals in a similar way to percentage.

#1 = 100/100 = 100%, 0 = 0%, 0.5 =50/100= 50%#

You will notice that #50 = 0.5 xx 100#, so that is what we will do to our decimal.

#0.15 xx 100% =15%#

Hope this helps; let me know if I can do anything else for you:)

#15%#

Explanation:

Remember this:

To convert a fraction or a number or a decimal, simply multiply it by #100%# to get the answer in percentage

So,

#3/20*color(blue)(100)%#

#3/cancel20^1*cancelcolor(blue)(100)^5%#

#15%#

Hope this helps... :)

#3/20 color(red)(xx5/5) = 15/100 = 15%#

Explanation:

A percent is a value out of #100#, so one way to convert a fraction to a percent is to find an equivalent fraction with its denominator as #100#

#20# can be multiplied by #5# to make #100#.

#3/20 color(red)(xx5/5) = 15/100 = 15%#

Note that #color(red)(xx5/5)# is the same as #color(red)(xx1)# , which means that the value of the fraction does not change, only what it looks like changes.
