3/16 - 1/2

You want to make the denominators the same.

So what number do you multiply by 2 to get 16? That number is 8. So you multpily the numerator and denomiator of the (1/2) by 8

So you will have:

3/16 - (1*8)/(2*8) = 3/16 - 8/16

Now since denominators are the same, we can then easily add/subtract the numerators

(3-8)/16 = -5/16

If you have any question about this solution let me know.
