TalentJR apps
In a hurry you rarely need the exact percent — you need a close one. Round the amount to a round hundred, round an awkward percent to a friendly one, and build it from blocks you can find instantly: 10% (÷ 10), 5% (half of that) and 1% (÷ 100).
✓ You passed this lesson’s test.
Round and build — “round to friendly numbers, then build the percent from 10%, 5% and 1%”
Use it for: Sale discounts in a shop, tips, GST on a bill, and multiple-choice percentage questions.
Check: 21% of 398 = 83.58, and 80 is the closest option ✓
Work it out in your head or on paper, type the answer and press Check. Stuck? Press “Show me how”.
