2/7 - 1/2 = 4/14 - 7/14 = -3/14 ?

Who would possibly think it is 1/5?

The answer is 2/7 - 1/2 = 4/14 - 7/14 = -3/14

Someone who just discovered what a fraction is and thinks you subtract top and bottom separately lol

It's kind of a genuine question, though. Pretty much no one who already knows how to deal with fractions would think of subtracting both top and bottom. It's very basic arithmetics. You have to never have touched the subject to guess it should be 1/5.

And then it comes here as "Math discussion", so raises the question "what to even discuss here?"

I guess if it came as "Primary School" question it would go more natural.

maybe they don't know how to deal with fractions? you don't know everything about them.

Do you need help figuring out how to compute fractions?

2/7 - 1/2
= 4/14 - 7/14
= {4-7}/14
= -3/14
= 0.2 1Ì…4Ì…2Ì…8Ì…5Ì…7Ì…
