Introduction

In this article, we will delve into a mathematical puzzle that involves a simple yet intriguing equation. The problem states that the difference of a number and 43\frac{4}{3} is 113\frac{11}{3}. Our goal is to identify the unknown number that satisfies this condition. To begin, we need to write an equation that describes the situation.

Writing the Equation

Let's denote the unknown number as xx. The problem states that the difference between this number and 43\frac{4}{3} is 113\frac{11}{3}. Mathematically, we can represent this as:

x43=113x - \frac{4}{3} = \frac{11}{3}

This equation tells us that the unknown number xx minus 43\frac{4}{3} equals 113\frac{11}{3}.

Solving the Equation

To find the value of xx, we need to isolate it on one side of the equation. We can do this by adding 43\frac{4}{3} to both sides of the equation. This will cancel out the 43\frac{4}{3} on the left-hand side, leaving us with the value of xx.

x43+43=113+43x - \frac{4}{3} + \frac{4}{3} = \frac{11}{3} + \frac{4}{3}

Simplifying the left-hand side, we get:

x=113+43x = \frac{11}{3} + \frac{4}{3}

Now, let's add the fractions on the right-hand side. Since they have the same denominator, we can simply add the numerators:

x=11+43x = \frac{11 + 4}{3}

x=153x = \frac{15}{3}

Simplifying the Fraction

The fraction 153\frac{15}{3} can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3. This gives us:

x=15÷33÷3x = \frac{15 \div 3}{3 \div 3}

x=51x = \frac{5}{1}

x=5x = 5

Conclusion

In this article, we have successfully unraveled the mystery of the unknown number. By writing an equation that describes the situation, we were able to isolate the value of xx and find that it equals 5. This demonstrates the power of algebra in solving mathematical puzzles and equations.
