115

Step-by-step explanation:

it is 115 because 50% is also known as 1 half so you do not have to do a load of working out but say if it was 35% percent it would be more difficult because you would have to divide by 10 to find 10% and then times it by 3 and then divide it by 100 then times it br % to find the 1

Answer:

115.

Step-by-step explanation:

50% is half of 100%, so all that is needed is to divide the number by 2 or:

230 * 50% =

230 * .5 = 1150

and once you move the decimal point back one, you end up with:

115.
