We know that 15 elves represent the 20% of the total.

Since 20% is one-fifth, the total number of elves is

15\cdot 5 = 75

Alternatively, solve the proportion

15\div x = 20\div 100

which yields

x=\dfrac{1500}{20}=75

Bill's original ratio is like this...
6 to 10

You need to solve for this...

Your new ratio is 90 to 150
Which reduces to 3 to 5

Yout new ratio is 3 to 5
