What is 2 divided by 5 plus 3 divided by 4 minus 1 divided by 2?

Answer 1

If your question is what is:

(2/5) + (3/4) - (1/2) = ?

then your answer would be (.4) + (.75) - (.5) = .65

However, if your question is what is:

2/5+3/4-1/2=?

then your answer would be 2/5=.4+3=3.4/4=.85-1=-.15/2=-.075
