Solving the Problem: 0.15 of What Number is 12
In mathematics, solving a problem that involves finding the original number when given a percentage of that number can be a bit challenging. In this article, we will solve the problem "0.15 of what number is 12" step by step.
Understanding the Problem
The problem asks us to find the original number that, when multiplied by 0.15, gives us 12. We can rewrite this problem as:
0.15 × x = 12
where x is the original number we are trying to find.
Solving the Problem
To solve this problem, we can begin by dividing both sides of the equation by 0.15.
x = 12 ÷ 0.15
To divide a number by a decimal, we can convert the decimal to a fraction and then perform the division.
x = 12 ÷ (15/100)
To divide by a fraction, we can multiply by the reciprocal of the fraction.
x = 12 × (100/15)
Now, we can perform the multiplication:
x = 80
Answer
Therefore, the original number that, when multiplied by 0.15, gives us 12 is 80.
In summary, the problem "0.15 of what number is 12" can be solved by dividing 12 by 0.15, which gives us the answer 80.
