Question

pratik ad rupees 50. he spent rupees 25 1/8on books and rupees 12 1/4 on food. how much money is left with him?

Answer 1

Hi Vera, set this up as an addition / subtraction problem.

 

50 - 25 1/8 - 12 1/4

 

Find the common denominator:

 

The common denominator for 4 and 8 is 8. Convert all values to fractions with the denominator of 8.

 

50 * 8 = 400

 

25 * 8 = 200

 

12 * 8 = 96

 

1/4 = 2/8

 

The problem becomes:

 

400 / 8 - 201 / 8 - 98 / 8 = 400 / 8 - 299 / 8 = 101 / 8

 

Finish by converting 101 / 8 to a mixed fraction:

 

101 / 8 = 12 and 5 / 8

 

Pratik had 12 and 5 / 8 rupees remaining.
