Solution
`bb(15/25)`
Explanation:
In order to find which of the given fraction is not equal to others, we will convert each of the given fraction in its lowest form. Now,
a. `6/8 = (6 ÷ 2)/(8 ÷ 2) = 3/4` ...[∵ HCF of 6 and 8 is 2]
b. `12/16 = (12 ÷ 4)/(16 ÷ 4) = 3/4` ...[∵ HCF of 12 and 16 is 4]
c. `15/25 = (15 ÷ 5)/(25 ÷ 5) = 3/5` ...[∵ HCF of 15 and 25 is 5]
d. `18/24 = (18 ÷ 6)/(24 ÷ 6) = 3/4` ...[∵ HCF of 18 and 24 is 6]
Hence, `15/25` is not equal to the others.
