Remember! Quotient 0.15 5 0.75 Divisor Dividend

Example 1: Dividing a Decimal by a Whole Number Find the quotient. A. 0.84 ÷ 3 0. 2 8 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. 3 0.84 – 6 24 – 24

Example 1: Dividing a Decimal by a Whole Number Find the quotient. B. 3.56 ÷ 4 0. 8 9 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. 4 3.56 – 32 36 – 36

You Try! Example 1 Find the quotient. A. 0.72 ÷ 3 0. 2 4 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. 3 0.72 – 6 12 – 12

You Try! Example 1 Find the quotient. B. 2.96 ÷ 4 0. 7 4 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. 4 2.96 – 28 16 – 16

Example 3: Consumer Application Jodi and three of her friends are making a tile design. The materials cost $10.12. If they share the cost equally, how much should each person pay? $10.12 should be divided into four equal groups. Divide $10.12 by 4. $2. 5 3 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. 4 $10.12 – 8 21 – 20 12 – 12 Each person should pay $2.53.

You Try! Example 3 Ty and three of his friends are building a fence. The lumber costs $21.44.
