40 is 20% of x. if x is 80% of y, then what is the sum of x and y?

40 is 20% of x

40 = .2 * x

40/.2 = x

x =200

x is 80% of y

x = .8 * y

200 = .8 *y

200/.8 = y

250 =y

x+y

200+250

450

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
