Lesson preview
This is the real lesson text your child hears, read aloud by a friendly voice.
Add and subtract decimals by lining up the decimal points: 12.75 + 3.6 = 16.35.
Multiply decimals, then count the decimal places: 1.25 × 0.4 = 0.5.
To divide by a decimal, move both points to make the divisor whole: 4.8 ÷ 0.6 = 48 ÷ 6 = 8.
Big whole number division uses the same steps: 7,488 ÷ 24 = 312.
