What is 4 over 6 minus 1 over 2?

Answer 1

With a calculator, multiplication, division, addition, and subtraction operations are done in that priority/sequence.

So, in your expression, 'over' is handled first, then 'minus'.

The question becomes 'what is (4/6) minus (1/2)?'

4/6 - 1/2 = 4/6 - 3/6 = 1/6
