38Here are two strategies to divide a decimal
less than 1 by a whole number.
® Use Base Ten Blocks.
• To divide 0.8 by 2:
0.8 is eight tenths.
Eight tenths divided by 2 is 4 tenths.
So, 0.8
2
0.4
• To divide 0.15 by 3:
0.15 is fifteen hundredths.
Fifteen hundredths divided by 3 is 5 hundredths.
So, 0.15

0.05
® Use place value.
To divide 0.074 by 8:
Estimate first. 0.074 is close to 0.072.
0.072 is 72 thousandths.
Seventy-two thousandths divided by 8 is 9 thousandths.
We know 72
8
9.
So, 0.074
8 is about 0.009.
