Finding Percent of a Number

Front

What is a percent?

A percent is a way to express a number as a fraction of 100. It is denoted by the symbol '%'. For example, 50% means 50 out of 100.

How do you find 60% of a number?

Back

To find 60% of a number, multiply the number by 0.60 (or 60/100). For example, to find 60% of 120, calculate 120 x 0.60 = 72.

Front

If you have a total amount and know the percent saved, how do you find the remaining amount needed?

Back

Subtract the amount saved from the total amount. For example, if you need $120 and saved 60%, you have saved $72, so you need $120 - $72 = $48.

Front

What is the formula to calculate the percent spent from a total amount?

Back

The formula is: (Amount Spent / Total Amount) x 100. For example, if you spent $21 from a $300 paycheck, the percent spent is (21/300) x 100 = 7%.

Front

How do you calculate the number of items based on a given percent?

Back

Multiply the total number of items by the percent (as a decimal). For example, if there are 400 baseball gloves and 30% are left-handed, calculate 400 x 0.30 = 120 left-handed gloves.

Front

What is the relationship between part, whole, and percent?

Back

The relationship can be expressed as: Percent = (Part / Whole) x 100. This means the part is a fraction of the whole expressed as a percent.

Front

How do you convert a percent to a decimal?

Back

To convert a percent to a decimal, divide the percent by 100. For example, 25% as a decimal is 25/100 = 0.25.

Front

What is the process to find the total amount if you know the part and the percent?

Back

Use the formula: Total Amount = Part / (Percent as a decimal). For example, if 12 students represent 24% of the choir, the total is 12 / 0.24 = 50 students.

Front

How do you calculate the amount spent based on a budget and percent?

Back

Multiply the budget by the percent spent (as a decimal). For example, if the budget is $9000 and 6% is spent, calculate $9000 x 0.06 = $540.

Front

What does it mean if a number is 30% of another number?

Back

It means that the first number is 30 out of every 100 parts of the second number. For example, if 30% of 400 is 120, then 120 is 30% of 400.
