If the numerator of a fraction is decreased 25 percent and the denominator of that fraction is increased 25 percent,
then the difference between the resulting and the original fractions represent what percentage decrease?
:
n%2Fd - %28.75n%29%2F%281.25d%29 = %281.25dn+-+.75dn%29%2F%281.25d%5E2%29 = %28.5dn%29%2F%281.25d%5E2%29 = %28.5n%29%2F%281.25d%29 = n%2F%282.5d%29 = .4(n%2Fd)
a 40% decrease
