Decimals

Fractions and decimals are the same amount

You will turn 7/10 into 0.7 (and back), say which is bigger, and find the missing mark on a 0–1 line. Denominators are only 10 or 100. On More difficult you also add and subtract decimals — lining up the places, never going below zero.

Watch the place: 0.7 is seven tenths, 0.07 is seven hundredths. 3/10 and 0.30 are equal.
