# CONVERTING BETWEEN PERCENTS DECIMALS AND FRACTIONS

Converting Between Percents Decimals and Fractions :

To solve many real world problems, we need to do conversions between percents, decimals and fractions.

Let us see how to do conversions between percents, decimals and fractions.

## A half can be written as given below ## A quarter can be written as given below ## CONVERSIONS

Problem 1 :

Convert the percentage given below into a proper fraction

2.4%

Solution :

2.4%  =  2.4/100  =  24/1000  =  3/125

Hence the proper fraction equal to the given percentage is 3/125

Problem 2 :

Convert the percentage given below into a proper fraction

0.55%

Solution :

0.55%  =  0.55/100  =  55/10000  =  11/2000

Hence the proper fraction equal to the given percentage is 11/2000.

Problem 3 :

Convert the percentage given below into a proper fraction

0.25%

Solution :

0.25%  =  0.25/100  =  25/10000

Hence the proper fraction equal to the given percentage is 1/400.

Problem 4 :

Convert the percentage given below into an improper fraction

125%

Solution :

125%  =  125/100  =  5/4

Hence the improper fraction equal to the given percentage is 5/4

Problem 5 :

Convert the percentage given below into an proper fraction

15%

Solution :

15%  =  15/100  =  3/20

Hence the improper fraction equal to the given percentage is 3/20

Problem 6 :

Convert the given fraction into decimal

3/20

Solution :

In  the given fraction, the denominator is 20 which is convertible to 100 using multiplication by 5.

So, we have

3/20  =  (3 ⋅ 5) / (20 ⋅ 5)  =  15 / 100  =  0.15

Hence,  3/20  =  0.15

Problem 7 :

Covert the given fraction into decimal

7/10

Solution :

In  the fraction, the denominator is 10.

So, we have

7/10  =  0.7

Hence,  7/10  =  0.7

Problem 8 :

Covert the fraction into decimal

3/50

Solution :

In the fraction number, the denominator is 50 which is convertible to 100 using multiplication by 2.

So, we have

3/50  =  (3 ⋅ 2) / (50 ⋅ 2)  =  6/100  =  0.06

Hence,  3/50  =  0.06

Problem 9 :

Covert the given fraction into decimal

1/2

Solution :

In the fraction, the denominator is 2 which is convertible to 10 using multiplication by 5.

So, we have

1/2  =  (1 ⋅ 5) / (2 ⋅ 5)  =  5/10  =  0.5

Hence,  1/2  =  0.5

Problem 10 :

Covert the fraction into decimal

3/4

Solution :

In  the fraction, the denominator is 4 which is convertible to 100 using multiplication by 25.

So, we have

3/4  =  (3 ⋅ 25) / (4 ⋅ 25)  =  75/100  =  0.75

Hence,  3/4  =  0.75

Problem 11 :

Convert the fraction into percentage.

2/3

Solution :

Here, the denominator of the given fraction is 3 which can not be converted into 100 using multiplication.

So the given fraction can be converted into decimal using long division.

So, 2/3  =  0.6666  (approximately)

0.6666  =  0.6666  100 %  =  66.66%

Hence, 2/3  =  66.66 %

Problem 12 :

Convert the given fraction into percentage.

5/6

Solution :

Here, the denominator of the given fraction is 6 which can not be converted into 100 using multiplication.

So the given fraction can be converted into decimal using long division.

So, 5/6  =  0.8333  (approximately)

0.8333  =  0.8333  100 %  =  83.33%

Hence, 5/6  =  83.33%

Problem 13 :

Convert the given fraction into percentage.

5/12

Solution :

Here, the denominator of the given fraction is 12 which can not be converted into 100 using multiplication.

So the given fraction can be converted into decimal using long division.

So, 5/12  =  0.4166  (approximately)

0.4166  =  0.4166  100 %  =  41.66%

Hence, 5/12  =  41.66 %

Problem 14 :

Convert the given fraction into percentage.

45/8

Solution :

Here, the denominator of the given fraction is 8 which can not be converted into 100 using multiplication.

So the given fraction can be converted into decimal using long division.

So, 45/8  =  5.625

5.625  =  5.625  100 %  =  562.5 %

Hence, 45/8  =  562.5 %

Problem 15 :

Convert the given fraction into percentage.

10/3

Solution :

Here, the denominator of the given fraction is 3 which can not be converted into 100 using multiplication.

So the given fraction can be converted into decimal using long division.

So, 10/3  =  3.3333  (approximately)

3.3333  =  3.3333  100 %  =  333.33 %

Hence, 10/3  =  333.33 % After having gone through the stuff given above, we hope that the students would have understood, how to do conversions between between percents decimals and fractions
