-2 · The hop moves 2 steps to the left of 0, landing on -2.
4 tenths (0.4) · The first digit after the decimal point is tenths, so 4 is worth 4 tenths, or 0.4.
False · -5 sits further left on the number line than -1, so -5 is smaller, not greater.
-2, 0, 1/2, 3 · Negative numbers come before 0, and positive numbers grow as you move right: -2, then 0, then 1/2 (0.5), then 3.
8 · After the decimal point: 2 is tenths, 8 is hundredths, 3 is thousandths.
Closer to 1 · 3/4 is three of four equal parts, more than halfway, so it sits closer to 1.
-2 · Halfway between -3 and -1 is -2, one step from each end.
He compared the digits instead of the place value · 0.7 equals 0.70. Comparing place by place, 70 hundredths is more than 65 hundredths, so 0.7 is bigger.
