Question:

2{1/4}% of 75


Answer:

Percents are a standard way of expressing a proportion (or fraction) relative to 100.

For example, when the weatherman says that chance of rain is 30%, that means that the chance of rain is 30 out of 100 (the fraction of 30/100). When the IRS says you must pay 25% income tax, that means that you must pay a tax of $25 for every $100 you earn (the fraction of 25/100).

To solve your problem, you must first convert the percent (2 and 1/4 %) to either a fraction whose denominator is 100, or to decimal.

For your problem, decimals will be easier to use. That is what I am going to demonstrate.


2 and 1/4 % = 2% + ¼%


2 and 1/4 % means a fraction (or proportion)
= 2/100 + ¼/100

= 0.02 + 0.0025

= 0.0225


2 and 1/4 % of 75 means 2 and 1/4 % multiplied by 75
(the word “of” stands for multiplication)

2 and 1/4 % multiplied by 75 = 0.0225 * 75 = 1.6875

The final answer to your question is:

2 and 1/4 % of 75 = 1.6875
