1/4 = 5/20
17/20-5/20 = (17-5)/20 = 12/20.
This fraction can be reduced as 12 and 20 both share 4 as common factors. Therefore 12/20 = 3/5.

The LCD is 20:
(17/20*1/1)-(1/4*5/5)
17/20-5/20
12/20
Reduce:
(12/4)/(20/4)=3/5

1/4 is 5/20, and I hope you can do
17/20 - 5/20
for yourself. But simplify your answer. It "cancels" down to a number of fifths.

12/20 which goes down to 6/10 which can also go down to 3/5.

This is not hard math. This is your second math problem you've posted. Figure it out, girl! Go back and read the lesson in your textbook if you don't understand, but you won't learn by having us give you all the answers. Come test time, Yahoo Answers won't be there to help!
