Question

A community food bank received 1,850 pounds of donated food in one week. Fresh produce made up 42% of the donated weight. How many pounds of fresh produce did the food bank receive?

777

Typed answer, rounded to a whole number.

Answer

777

Rationale

The produce is one part of the whole donation, so the total weight is multiplied by the produce percent written as a decimal. Writing 42% as a decimal means dividing 42 by 100, which moves the decimal point two places to the left.

Worked solution: 42% of 1,850 = 42 ÷ 100 × 1,850 = 777.

RememberPercent means per 100: move the decimal point two places left, then multiply by the whole.
