Will be marked brainliest and will get ! by what percent will a fraction change if its numerator is decreased by 50% and its denominator is decreased by 25%? show all your work when answering. you so much : d.

The percentage change is given by

... ((new value) - (old value))/(old value) × 100%

If the original fraction is 100/100, we can decrease its numerator by 50% by making it be 100-50 = 50. We can decrease its denominator by 25% by making it be 100-25 = 75. Then your percentage is ...

Note that we have taken advantage of the fact that 100/100 = 1 = 75/75 to simplify the expression dramatically.

The percentage change is -33.3%
