Answer:

#109/151 xx 100% = 72.2%#

Explanation:

It is easier to understand this if written the other way around.
What percent is #109 " out of " 151#?

Like " My mark was 20 out of 28 for the test. What percent is that?"

When you divide #109/151# the answer is already in decimal form.

#109/151 = 0.722# which means the same as #72.2/100#

NOte that this is already written as a percent (it is out of 100)

Let's change the format, without changing the value.

#109/151 xx 100% = 72.2%#

#xx 100% " is the same as " xx 1#
