Answer:

Question A:

1. 1/2  = 0.5 (Terminating)

2. 5/6  = 0.833333.. (Repeating)

3. 21/3 = 1.6666666.. (Repeating)

Question B:

1. 0.6  = 3/5

2. 1.25  = 5/4 = 1 1/4

3. 0.125 = 1/8

Step-by-step explanation:

A. Write the fraction or mixed number as a terminating or repeating decimal.

In order to convert a fraction into decimal, the numerator has to be divided by denominator.

1. 1/2

The answer is: 0.5 which is a terminating decimal.

2. 5/6

The answer is: 0.833333.. which is a repeating decimal.

3. 2 1/3 (assuming the question is this)

2\frac{1}{3} = \frac{7}{6} = 1.6666666..

The answer is 1.6666666.. which is a repeating decimal.

B. Write the terminating decimal as fraction or mixed number i n simplest form.

1. 0.6

0.6 = \frac{6}{10} = \frac{3}{5}

2. 1.25

1.25 = \frac{125}{100} = \frac{5}{4} = 1\frac{1}{4}

3. 0.125

0.125 = \frac{125}{1000} = \frac{5}{40} = \frac{1}{8}

Hence,

Question A:

1. 1/2  = 0.5 (Terminating)

2. 5/6  = 0.833333.. (Repeating)

3. 21/3 = 1.6666666.. (Repeating)

Question B:

1. 0.6  = 3/5

2. 1.25  = 5/4 = 1 1/4

3. 0.125 = 1/8
