CONVERTING FRACTION AS DECIMAL

Convert the following fraction as decimal.

Problem 1 :

1/2

Solution :

Numerator = 1, denominator = 2

By multiplying 2 by 5, we will get the denominator as 10.

= (1/2) x (5/5)

= 5/10

We have decimal after 5, we have one zero at the denominator. So, we have to move the decimal one digit towards left. So, the answer is 0.5

1/2 = 0.5

Problem 2 :

7/10

Solution :

Numerator = 7, denominator = 10

Already the denominator is in the form 10ⁿ . We have one zero at the denominator, we have to move the decimal one digit left. So, the answer is 0.7

7/10 = 0.7

Problem 3 :

1/5

Solution :

Numerator = 1, denominator = 5

= (1/5) x (2/2)

= 2/10

= 0.2

Problem 4 :

3/4

Solution :

Numerator = 3, denominator = 4

4 should be multiplied by 25 to make it as 100.

= (3/4) x (25/25)

= 75/100

= 0.75

Problem 5 :

1/10

Solution :

Numerator = 1, denominator = 10

It is in the form of 10ⁿ. Moving the decimal one digit towards left, we get

= 0.1

Problem 6 :

9/10

Solution :

Numerator = 9, denominator = 10

It is in the form of 10ⁿ. Moving the decimal one digit towards left, we get

= 0.9

Problem 7 :

4/5

Solution :

Numerator = 4, denominator = 5

= (4/5) x (2/2)

= 8/10

It is in the form of 10ⁿ. Moving the decimal one digit towards left, we get

= 0.8

Problem 8 :

4/50

Solution :

Numerator = 4, denominator = 50

To make 50 as in the form of 10ⁿ, we have to remember 2 x 50 = 100

= (4/50) x (2/2)

= 8/100

Moving the decimal two digits towards left, we get

= 0.08

Problem 9 :

8/25

Solution :

Numerator = 8, denominator = 25

To make 25 as in the form of 10ⁿ, we have to remember 25 x 4 = 100

= (8/25) x (4/4)

= 32/100

Moving the decimal 2 digits left, we get

= 0.32

Problem 10 :

7/20

Solution :

Numerator = 7, denominator = 20

To make 20 as in the form of 10ⁿ, we have to remember 20 x 5 = 100

= (7/20) x (5/5)

= 35/100

Moving the decimal 2 digits left, we get

= 0.35

Problem 11 :

7/25

Solution :

Numerator = 7, denominator = 25

To make 25 as in the form of 10ⁿ, we have to remember 25 x 4 = 100

= (7/25) x (4/4)

= 28/100

Moving the decimal 2 digits left, we get

= 0.28

Problem 12 :

2/3

Solution :

Numerator = 2, denominator = 3

To convert it as a decimal, we may use the long division.
