Answer:21.9FM
Step-by-step explanation:
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
