Hey guys i need quick man help, please
Calculate the following
a, what is 30% of 45
b,what is 20% of 80
please help me.. i forgot how to do over the holidays.
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?
