# Solving for What Number is 10.4 of It Equal to 13

The question of what number is 10.4 of it equal to 13 is a common math problem. People often ask this question when they are trying to solve a math problem or when they are trying to figure out how much of something they need to buy. In this article, we will explain how to solve this problem using simple math principles.

## Understanding the Concept of Fraction The first thing to understand when it comes to solving this problem is the concept of fraction. A fraction is a mathematical expression that represents a part or a portion of a whole. For example, if we have a pizza and divide it into four slices, each slice would be one-fourth of the whole pizza. In this case, the fraction would be 1/4.

## Using the Concept of Fraction to Solve the Problem Now that we understand the concept of fraction, we can use it to solve the problem. In this problem, 10.4 is the fraction of a number that is equal to 13. To solve this problem, we need to determine what the whole number is. To do this, we can use the following equation:

Whole Number = 13 / 10.4

By solving this equation, we can determine that the whole number is 12.5. This means that 10.4 of 12.5 is equal to 13.

## Using Other Methods to Solve the Problem In addition to using the concept of fraction to solve this problem, there are other methods that can be used. For example, we can use multiplication or division to solve the problem. If we use multiplication, the equation would be:

Whole Number = 13 / (10.4 x 1)

If we use division, the equation would be:

Whole Number = 13 x (1 / 10.4)
