Answer 2

Answer:

Option (B) 15/20, is not the lowest form.

Step-by-step explanation:

Lowest Form:- A fraction is said to be in its lowest form when its numerator or denominator is relatively prime, which means they have no factor in common except 1.

For example, 5/6 is written in its lowest form, as 5 and 6 don't have any common factor except 1.

Now, according to the question 7/5, 13/33, 27/28 is in its lowest form.

Except 15/20, as it can be divided by 5, we get 3/4.

∴ 15/20 is not in its lowest form in accordance to the following options.

Hence option (B) is the correct answer.
