• 0.24 ÷ 4 = 0.06

• 0.96 ÷ 4 = 0.24

What decimal division problem is represented by the model?

• 1.26 ÷ 3 = 0.42

• 42 ÷ 3 = 14

• 12.6 ÷ 3 = 4.2

What decimal division problem is represented by the model?

• 2.10 ÷ 5 = 0.42

• 10.05 ÷ 5 = 2.01

• 10.5 ÷ 5 = 2.1

What decimal division problem is represented by the model?

• 4.88 ÷ 2 = 2.44

• 4.44 ÷ 2 = 2.22

What decimal division problem is represented by the model?

• 6 ÷ 0.02 = 0.3

Which model represents 0.84 ÷ 4?

• 
• 
• 

Answer explanation

The question asks, "How many will be in each group if we divide 84 hundredths into 4 equal groups?" The answer (quotient) is... "There will be 0.21 in each group." The only model that shows 21 hundredths in each group is the model shown.

What decimal division problem is represented by the model?

• 24 ÷ 6 = 4

• 2.4 ÷ 0.4 = 0.6

• 2.4 ÷ 4 = 0.6

What decimal division problem is represented by the model?

• 2.7 ÷ 9 = 0.03

• 0.27 ÷ 3 = 0.09

• 0.27 ÷ 0.09 = 0.3

Answer explanation

Here, 27 hundredths are divided into 3 equal groups OR groups of 9 hundredths. The answer must be 0.27 ÷ 3 = 0.09 (shown) OR 0.27 ÷ 0.09 = 3, which is not an option.

What decimal division problem is represented by the model?

• 0.42 ÷ 6 = 0.07

• 0.42 ÷ 6 = 0.7

• 0.42 ÷ 7 = 0.06
