Answer 2

Step-by-step explanation:

We already have our first value 12 and the second value 30. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 12 = 30% × Y

STEP 2 12 =

30

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:

STEP 3 Y = 12 ×

100

30

STEP 4 Y = 12 × 100 ÷ 30

STEP 5 Y = 40
