Name: Karen Question: Hi I need to simplify this a) 3pi/2  pi the example is this : =3pi/3  pi/3 =2pi/3 The answer to a) is pi/2, I just can't figure out why. Thanks. Hi Karen,
You are to subtract pi from 3pi/2. If you think of pi as the fraction pi/1 then the problem is to subtract two fractions Penny
