I only need the first one ( 45% of 30) but please keep in mind that I do need help with the other two, but they are optional.
What is 45% of 30?
What is 40% of 175?
What is 20% of 60?
45%=.45=45/100 take 45/100 * 30 = 45*30/100 Honestly you can leave it as a fraction since it is rational and all rationals can be represented as a/b repeat process for 2 and 3
