Question

By what will the product of 2 numbers decrease if one of the numbers is decreased by 25% and the other number is decreased by 50%

Answer 1

62.5%

Explanation:

the product of the two numbers=xy

the product of the altered numbers=(0.75x)(0.5y) OR 0.375xy

finally you subtract this from one to get your decrease: 1-0.375=0.625

then simply convert that to a percent, leaving you with 62.5%. hope this helps!
