Introduction

In this article, we will explore how to calculate complex fractions without the use of a calculator. We will focus on a specific example, $\frac{50 \times 33 + 25 \times 50}{10 \times 50 - 50 \times 19}$ , and break it down into manageable steps. By the end of this article, you will have a clear understanding of how to approach and solve complex fractions without relying on technology.

Breaking Down the Problem

To start, let's examine the given fraction: $\frac{50 \times 33 + 25 \times 50}{10 \times 50 - 50 \times 19}$ . Our goal is to simplify this expression and arrive at a final answer without using a calculator.

Step 1: Multiply the Numbers

The first step is to multiply the numbers in the numerator and denominator. In the numerator, we have $50 \times 33$ and $25 \times 50$ . In the denominator, we have $10 \times 50$ and $50 \times 19$ .

Numerator: 50 × 33 = 1650
Numerator: 25 × 50 = 1250
Denominator: 10 × 50 = 500
Denominator: 50 × 19 = 950

Step 2: Add and Subtract the Results

Now that we have the results of the multiplications, we can add and subtract them to simplify the expression.

Numerator: 1650 + 1250 = 2900
Denominator: 500 - 950 = -450

Step 3: Simplify the Fraction

With the numerator and denominator simplified, we can now simplify the fraction by dividing the numerator by the denominator.

Fraction: 2900 ÷ -450 = -6.44 (approximately)

Step 4: Final Answer

After simplifying the fraction, we arrive at our final answer: -6.44 (approximately).

Conclusion

In this article, we demonstrated how to calculate a complex fraction without the use of a calculator. By breaking down the problem into manageable steps and using basic arithmetic operations, we were able to simplify the expression and arrive at a final answer. This approach can be applied to a wide range of complex fractions, making it an essential skill for anyone working with mathematical expressions.
