Question

Which represents faster growth, a growth factor of 2.5 or a growth rate of 25% ?

Answer 1

To compare factors we have to transform both to the same unit. Lets create 25% into decimal
25%=0.25
Now we can compare 25% and 0.25 and we see that 2.5 is greater.
Answer: faster growth factor its 2.5.

Answer 2

FYI this is the english section not the math section
anyway

a grouth rate of 25% means that 25/100

a factor of 2.5 means 250/100 or 250%


so 2.5 is greater
