100% is one whole. More than 100% means more than one whole; less than 1% is a tiny sliver. To handle these you read place value and slide the decimal by 10s and 100s. Warm those up first.
Answer these 3, then press Show my path. No grade — this just points you to the right level.
1. 100% of something means…
2. What is 3 × 100?
3. What is 5 ÷ 100?
100% = one whole. A percent over 100 is more than a whole; a percent under 1 is a sliver. To turn a percent into a decimal, divide by 100 (slide the dot 2 places left).
Your quick check picks one for you, but you can switch any time:
Level 0 Warm up wholes and place value.
A. 100% of a pizza means how many whole pizzas?
100% is one whole.
B. What is 2 × 100?
2 hundreds = 200.
C. What is 1 ÷ 100?
Dividing by 100 slides the dot 2 places left: 1 → 0.01.
Level 1 Read big and small percents.
A. Which percent is MORE than one whole?
100% is one whole, so 150% is more than one whole.
B. Write 200% as a number of wholes.
200 ÷ 100 = 2 wholes.
C. Which percent is the SMALLEST?
0.5% is less than 1% — the tiniest of these.
Level 2 Stretch into decimals.
A. Write 150% as a decimal.
150 ÷ 100 = 1.5.
B. Write 0.5% as a decimal.
0.5 ÷ 100 = 0.005.
1. Which percent means MORE than one whole?
Anything above 100% is more than one whole; 300% = 3 wholes.
2. What is 4 × 100?
4 hundreds = 400.
