Answer: 12 is 30 percent of 40

A simple step by step solution for calculating 12 is what percent of 40

We already have our first value 12 and the second value 40. 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 Y = 12/40

By multiplying both numerator and denominator by 100 we will get:

STEP 2 Y = 12/40 × 100/100 = 30/100

STEP 3 Y = 30

Finally, we have found the value of Y which is 30 and that is our answer.

Computing the left side, we get: 30 = Y

This leaves us with our final answer: 12 is 30 percent of 40
