40. Think about it like this, 50 percent of something is half of it. If you divide 80 by 2 you will get 40! Also you can multiply 80 by the decimal equivalent of 50% which is .5! so 80 * .5 =40!!
Change percent into decimal which is 0.80 and multiply it by 80 to get 40 which is the answer Also since 50% is half you could just divide 80 by 2
