some vocabulary:

"percent" means "out of 100", or "over 100"

"is" means "equals"

"of" in math usually means "multiply"

so to answer part (a) for instance, we would say:

"30% of 45 is ..." which translates to "$\displaystyle \frac {30}{100} \times 45 = \cdots$"

so now you can find that. what do you get for the answer? can you do the second one? - Jan 3rd 2009, 07:20 PMmr fantastic
