Spectrum Math Grade 5 Chapter 3 Lesson 3.10 Dividing Decimals Using Models Answers Key
Draw models to solve the problems.
Question 1.
2.4 ÷ 0.8 = _____
Answer:
Observe the value of the dividend and the divisor in the division equation or problem. Shade the model as per the value of the dividend and then divide the shaded portion into equal groups of the same size as the divisor. Then, the quotient will be the size of each equal group.
– Here we have three groups containing 8-tenths.
2.4 ÷ 0.8 = 3
Therefore, the answer is 3.
Question 2.
1.6 ÷ 0.4 = _____
Answer:
Observe the value of the dividend and the divisor in the division equation or problem. Shade the model as per the value of the dividend and then divide the shaded portion into equal groups of the same size as the divisor. Then, the quotient will be the size of each equal group.
– Here we have four groups containing 4-tenths.
1.6 ÷ 0.4 = 4
Therefore, the answer is 4.
Question 3.
1.6 ÷ 0.8 = _____
Answer:
Observe the value of the dividend and the divisor in the division equation or problem. Shade the model as per the value of the dividend and then divide the shaded portion into equal groups of the same size as the divisor. Then, the quotient will be the size of each equal group.
– Here we have two groups containing 8-tenths.
1.6 ÷ 0.8 = 2
Therefore, the answer is 2
Question 4.
1.4 ÷ 0.7 = _____
Answer:
Observe the value of the dividend and the divisor in the division equation or problem. Shade the model as per the value of the dividend and then divide the shaded portion into equal groups of the same size as the divisor. Then, the quotient will be the size of each equal group.
– Here we have two groups containing 7-tenths.
1.4 ÷ 0.7 = 2
Therefore, the answer is 2.
