Solve decimal division problems using the standard algorithm.
Practice Set C Answer Key
1. Solve each division problem:
.84 ÷ 0.6 = 1.4
1.68 ÷ 1.2 =1.4
.28 ÷ .2 =1.4
a. Write three more problems that belongs to this set.
Answers will vary. The dividend and divisor of any of the above problems can be
multiplied or divided by the same number. When the new numbers are divided,
the quotient will remain the same.
2. The circumference of a circle can be found by multiplying the diameter by π . The
following chart is missing the diameters of each circle. Find the diameter using 3.14 as
an approximation for π .
Circumference
Diameter
9.263 in.
2.95 in.
17.27 in.
5.5 in.
25.905 in.
8.25 in.
a. Explain how you were able to find the diameter of each circle. Be sure to
include any models or algorithms that were used to calculate the diameter.
The diameter can be found by dividing the circumference by the approximation
for π (3.14). Students should include representations of any models or algorithms
used to find the diameter in addition to explanations.
