To solve this, we need to first calculate what the unknown number is. We know that 12 is equivalent to 15 % of the number.

Let the unknown number = X

This means that 12 is to X as 15 is to 100

X 100

X = 12 ×

15

X = 80

So the number is 80. Now we need to find the 35 % of that number. This will be done is follows:

100

Let the unknown number = X

This means that 12 is to X as 15 is to 100

__12__=__15__X 100

X = 12 ×

__100__15

X = 80

So the number is 80. Now we need to find the 35 % of that number. This will be done is follows:

__35 .__× 80 = 28100
