Part - Whole - Percent Practice

Front

What is a part in a part-whole relationship?

Back

A part is a portion or segment of a whole. For example, if there are 10 apples and you have 3, then 3 is the part.

Front

What is a whole in a part-whole relationship?

Back

A whole is the total amount or entirety of something. For example, if there are 10 apples, then 10 is the whole.

Front

What is a percent?

Back

A percent is a way to express a number as a fraction of 100. For example, 50% means 50 out of 100.

Front

How do you find the whole when given a part and a percent?

Back

To find the whole, divide the part by the percent (in decimal form). For example, if 29 is 98%, the whole is 29 / 0.98.

Front

If 42 is what percent of 90, how do you find the percent?

Back

To find the percent, divide the part (42) by the whole (90) and multiply by 100. So, (42 / 90) * 100 = 46.67%.

Front

What is the formula to find a part when you have the whole and the percent?

Back

The formula is: Part = Whole x (Percent / 100). For example, if the whole is 90 and the percent is 76, then Part = 90 x (76 / 100) = 68.

Front

What does it mean if something is 100% of a whole?

Back

If something is 100% of a whole, it means you have the entire amount. For example, if you have 100% of 50 apples, you have all 50 apples.

Front

How do you convert a percent to a decimal?

Back

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

Front

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

Back

The relationship is defined as: Part = Whole x (Percent / 100). This shows how the part is derived from the whole and the percent.

Front

If you have 327 flair pens and sanitize 76%, how many pens are sanitized?

Back

To find the number of sanitized pens, use the formula: Part = Whole x (Percent / 100). So, Part = 327 x (76 / 100) = 248.52, rounded to 249 pens.
