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.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 How many you have for every 100.
Example: 25 out of 100 means 25 for each 100.
Level 1 All of one full thing, with no parts missing.
Example: A full pizza with every slice is one whole.
Level 1 To make a number 100 times bigger.
Example: 3 × 100 = 300.
Level 1 To make a number 100 times smaller by moving the dot two places left.
Example: 5 ÷ 100 = 0.05.
