To convert fraction as decimal, we have two different ways.
Using long division :
The given fraction is in the form a / b, in long division a should be written inside and b should be written outside and continue dividing it until we receive 0 as remainder.
Making the denominator as 10^{n} :
The tricks will be helpful to make the denominator as 10^{n}
After making the denominator as 10^{n}, based on the number of zeroes we have at the denominator we have to move the decimal towards the left.
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 10^{n} . 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 10^{n}. 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 10^{n}. 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 10^{n}. 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 10^{n}, 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 10^{n}, 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 10^{n}, 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 10^{n}, 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.
