Word problems with percents (tips, sales, scores) need you to read what's happening, take a percent of a number, and sometimes add or subtract. Warm up friendly percents and clean adding/subtracting first.
Answer these 3, then press Show my path. No grade — this just points you to the right level.
1. 10% of a number is found by…
2. What is 40 + 8?
3. What is 20 − 5?
Find the percent first, then decide whether to add it on (a tip) or subtract it off (a discount).
Your quick check picks one for you, but you can switch any time:
Level 0 One small step at a time.
A. 10% of 20 = ___ (20 ÷ 10).
20 ÷ 10 = 2.
B. Now add it on: 20 + 2 = ___?
20 + 2 = 22.
C. Take it off instead: 20 − 2 = ___?
20 − 2 = 18.
Level 1 Find the percent, then add or subtract.
A. 50% of 60 = ___?
Half of 60 is 30.
B. A $40 shirt, take 25% off (25% of 40 = 10). Sale price = 40 − 10 = ___?
40 − 10 = 30.
C. A $50 meal, add a 10% tip (10% of 50 = 5). Total = 50 + 5 = ___?
50 + 5 = 55.
Level 2 Full mini word problems.
A. A $80 bike is 25% off. How many dollars do you SAVE? (25% of 80)
80 ÷ 4 = 20 saved.
B. 10% tip on a $90 bill, then the TOTAL = 90 + (10% of 90) = ___?
10% of 90 = 9, so 90 + 9 = 99.
1. 10% of 40 = ___?
40 ÷ 10 = 4.
2. A $20 game is 50% off. Sale price = 20 − (50% of 20) = ___?
50% of 20 = 10, so 20 − 10 = 10.
