Answer:
Rahul has 3 3/4 more rice than Reena
Explanation:
first you have to make the two fractions a mixed fraction or improper fraction
7 1/2= 15/2
15/4= 15/4
now you have to see if they have the same denominator, they don't have the same denominator
the denominator i choose was 4
15/2 times 2/2= 30/4
15/4= 15/4
now you have to subtract the two fraction, to know the difference between them
30/4-15/4= 15/4 or 3 3/4
