Solve Percent Equations for the Part

Teach one unknown at a time with the first three sheets. Then use the word problem sheet to practice setting up equations and the mixed review to check that students can tell the three kinds apart.

Solve 14 percent equations for the part, such as 24% of 85 = n and 0.75% of 1,600 = n. The directions on the page read: Solve each equation for n. Write the percent as a decimal and multiply. Show your work. The page opens with a worked example, and an answer key is included.

Yes, both. We made it for 8th grade percents, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

Write the percent as a decimal and divide the part by it. For 65% of n = 117, 0.65n = 117, so n = 117 ÷ 0.65 = 180. Solve Percent Equations for the Whole has 14 equations like this.

Divide the part by the whole, then write the quotient as a percent. For n% of 160 = 52, 52 ÷ 160 = 0.325, so n = 32.5. Solve Percent Equations for the Percent practices this.

Choose a letter for the unknown and write the percent as a decimal times the whole. If 69 pages is 30% of a book, then 0.3p = 69 and p = 230 pages. Write and Solve Percent Equations has six problems to set up.
