Tips for Improving Your Score
Use these simple strategies to solve problems more accurately and efficiently.
Tip 1
Use fractional shortcuts: 50% = 1/2, 25% = 1/4, 75% = 3/4, and 10% = divide by 10.
Tip 2
To find 20%, find 10% first (move the decimal point one place left) and double the result.
Tip 3
To find 75%, find 50% and 25% and add them together, or subtract 25% from the original number.
Tip 4
All answers are whole numbers; if your calculation gives a fraction, recheck your steps.
