One half would equal 0.5 in decimal and in 1/2 in a fraction. On a calculator you could put the number one and divide it by 2 and it would give you 0.5 or you don’t have to put the zero, like for example it could just be .5 but what I’m trying to say is that in fraction one half would be 1/2 and in decimal 0.5 (.5)
