1. Write each of the following as decimals:

(i) Five hundred twenty five and forty hundredths.

(ii) Twelve and thirty five thousandths

(iii) Fifteen and seventeen thousandths

(iv) Eighty eight and forty eight hundredths

Solution:

(i) Five hundred twenty five and forty hundredths

It can be written as

525 + 40/100 = 525.40

(ii) Twelve and thirty five thousandths

It can be written as

12 + 35/1000 = 12.035

(iii) Fifteen and seventeen thousandths

It can be written as

15 + 17/1000 = 15.017

(iv) Eighty eight and forty eight hundredths

It can be written as

88 + 48/100 = 88.48

2. Write each of the following as decimals:

(i) 137 + 5/100

(ii) 20 + 9 + 4/100

Solution:

(i) 137 + 5/100

We know that

1 hundred, 3 tens, 7 ones and 5 hundredths

Hence, the decimal is 137.05.

(ii) 20 + 9 + 4/100

We know that

2 tens, 9 ones and 4 hundredths

Hence, the decimal is 29.04.

3. Write each of the following as decimals:

(i) 8/100

(ii) 300/1000

(iii) 18/1000

(iv) 208/100

(v) 888/1000

Solution:

(i) 8/100

We know that 8/100 = 0.08

Hence, the decimal is 0.08.

(ii) 300/1000

We know that 300/1000 = 3/10

So 3 tenths

Hence, the decimal is 0.3.

(iii) 18/1000

We know that 18/1000 = 0.018

Hence, the decimal is 0.018.

(iv) 208/100

We know that 208/100 = 200/100 + 8/100

So 2 and 8 hundredths

Hence, the decimal is 2.08.

(v) 888/1000

We know that 888/1000 = 800/1000 + 80/1000 + 8/1000

We get

= 8/10 + 8/100 + 8/1000

So 8 tenths, 8 hundredths and 8 thousandths

Hence, the decimal is 0.888.

4. Write each of the following as decimals:

(i) 12 1/4

(ii) 7 1/8

(iii) 5 1/20

Solution:

(i) 12 1/4

It can be written as

= 12 + 1/4

In order to make denominator 100

Multiply and divide by 25

We get

= 12 + [(1/4) × (25/25)]

On further calculation

= 12 + 25/100

So we get

= 12.25

(ii) 7 1/8

It can be written as

= 7 + 1/8

In order to make denominator 1000

Multiply and divide by 125

We get

= 7 + [(1/8) × (125/125)]

On further calculation

= 7 + 125/1000

So we get

= 7.125

(iii) 5 1/20

It can be written as

= 5 + 1/20

In order to make denominator 100

Multiply and divide by 5

We get

= 5 + [(1/20) × (5/5)]

On further calculation

= 5 + 5/100

So we get

= 5.05

5. Write each of the following decimals as fractions. Reduce the fractions to lowest form:

(i) 0.04

(ii) 2.34

(iii) 0.342

(iv) 1.20

(v) 17.38

Solution:

(i) 0.04

It can be written as

= 0 + 0.04

We get

= 0 + 4 hundredths

On further calculation

= 0 + 4/100

So we get

= 1/25

(ii) 2.34

It can be written as

= 2 + 0.34

We get

= 2 + 34 hundredths

On further calculation

= 2 + 34/100

So we get

= 2 × (100/100) + 34/100

By further simplification

= 200/100 + 34/100

= 234/100

By division

= 117/50

(iii) 0.342

It can be written as

= 0 + 0.342

We get

= 0 + 342 thousandths

On further calculation

= 342/1000

So we get

= 171/500

(iv) 1.20

It can be written as

= 1 + 0.20

We get

= 1 + 20 hundredths

On further calculation

= 100/100 + 20/100

So we get

= 120/100

By division

= 6/5

(v) 17.38

It can be written as

= 17 + 0.38

We get

= 17 + 38 hundredths

On further calculation

= 17 + 38/100

So we get

= 17 × (100/100) + 38/100

By further simplification

= 1700/100 + 38/100

= 1738/100

By division

= 869/50

6. Write each of the following as decimals:

(i) 20 + 9 + 40/10 + 1/100

(ii) 30 + 4/10 + 8/100 + 3/1000

(iii) 137 + 5/100

(iv) 7/10 + 6/100 + 4/1000

(v) 23 + 2/10 + 6/1000

(vi) 700 + 20 + 5 + 9/100

Solution:

(i) 20 + 9 + 40/10 + 1/100

We know that

2 tens, 9 ones, 4 tenths and 1 hundredths

Hence, the decimal is 29.41.

(ii) 30 + 4/10 + 8/100 + 3/1000

We know that

3 tens, 4 tenths, 8 hundredths and 3 thousandths

Hence, the decimal is 30.483.

(iii) 137 + 5/100

We know that

1 hundred, 3 tens, 7 ones and 5 hundredths

Hence, the decimal is 137.05.

(iv) 7/10 + 6/100 + 4/1000

We know that

7 tenths, 6 hundredths and 4 thousandths

Hence, the decimal is 0.764.

(v) 23 + 2/10 + 6/1000

We know that

2 tens, 3 ones, 2 tenths and 6 thousandths

Hence, the decimal is 23.206.

(vi) 700 + 20 + 5 + 9/100

We know that

7 hundreds, 2 tens, 5 ones and 9 hundredths

Hence, the decimal is 725.09.
