Write the following in decimal number. 2 5

Given fraction is 2 5 . We have to change the fraction so that the denominator becomes 10 , 100 , 1000 etc. By looking at the denominator, we have 5 × 2 = 10 So, multiplying both numerator and denominator by 2 , we get 2 5 = 2 × 2 5 × 2 = 4 10 Since, there is one zero after 1 in the denominator, put decimal point before one digit starting from extreme right in the numerator. Hence, 2 5 = 4 10 = 0 . 4

Write the following in decimal number 7 25

Given fraction is 7 25 We have to change the fraction so that the denominator becomes 10 , 100 , 1000 etc. By looking at the denominator, we have 25 × 4 = 100 So, multiplying both numerator and denominator by 4 , we get 7 25 = 7 × 4 25 × 4 = 28 100 Since, there are two zeros after 1 in the denominator, put a decimal point before two digits starting from the extreme right in the numerator. Hence, 7 25 = 28 100 = 0 . 28 .

Write the following in decimal number 27 50

Given the fraction 27 50 We have to change the fraction so that the denominator becomes 10 , 100 , 1000 etc. By looking at the denominator, we have 50 × 2 = 100 So, multiplying both numerator and denominator by 2 , we get 27 50 = 27 × 2 50 × 2 = 54 100 Since, there are two zeros after 1 in the denominator, put decimal point before two digits starting from extreme right in the numerator. Hence, 27 50 = 54 100 = 0 . 54

Write the following in decimal number. 47 100

Given the fraction 47 100 Since, there are two zeros after 1 in the denominator, put decimal point after two digits starting from extreme right in the numerator. Hence, 47 100 = 0 . 47
