Find the Missing Number in Percent Problems
Written by Adi Ackerman, Head Teacher
"Find the Missing Number in Percent Problems" is written for 6th Grade (Ages 11-12), and it covers Common Core 6.RP.A.3.C. If your student is a year younger but already steady on percents, the page still works. You may just need to read the instructions out loud. And if they are older and percent of a number never quite stuck, this is a short review rather than busywork.
6th grade math worksheet: find the missing number in 16 percent sentences, such as 60% of what number equals 24. Answer key included. Part of our percent of a number percents collection. Aligned to Common Core standards.
How do I use this worksheet?
Start with the multiples of 10 page to build the 10% strategy, then move to the decimal multiplication pages. Use the missing number page last, since it runs the idea backward.
What students will practice
- Students will find the missing whole in percent sentences such as 80% of a number = 60.
- Students will find the missing percent in sentences such as what percent of 120 = 18.
- Students will complete 16 percent sentences using percent as a ratio out of 100.

What does this worksheet teach?
⌄
Find the missing number in 16 percent sentences, such as 60% of what number equals 24. A percent is a ratio out of 100: 30% of 50 = 15, since 30 out of 100 equals 15 out of 50. The directions on the page read: Find the missing number in each percent sentence. An answer key is included.
Can I use this percent of a number worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 6th Grade percents, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with percent of a number. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How do you find the percent of a number?
⌄
Write the percent as a decimal and multiply. 17% of 300 = 0.17 × 300 = 51, and 25% of 8.4 = 0.25 × 8.4 = 2.1.
What is a quick way to find 30% or 40% of a number?
⌄
Find 10% first by dividing by 10, then multiply. 10% of 650 is 65, so 40% of 650 is 4 × 65 = 260.
How do you find the missing number in a percent problem?
⌄
Work backward from the part you know. If 60% of a number is 24, then 10% is 4, so the whole number is 40.
Can a percent be more than 100%?
⌄
Yes. A percent over 100% gives more than the number, so 300% of 14 = 3 × 14 = 42. Find Hundreds of Percents of a Number has 24 of these problems.
