Rahul bought 7 1/2 kg of rice and Reena bought 15/4 kg of rice. Who bought more rice and by how much?

rahul bought more

Step-by-step explanation:

7 1/2 kg is the same as 15/2

then you simplify 15/4 to 7.5/2

now both fractions have same denominators so compare

15 is bigger than 1.5

Rahul has 3 3/4 more rice than Reena

Step-by-step 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
