Introduction

In mathematics, simplifying complex fractions is an essential skill that helps us solve problems efficiently. A complex fraction is a fraction that contains one or more fractions in its numerator or denominator. In this article, we will focus on simplifying a specific complex fraction: $\frac{3}{5} \times \frac{10}{12} \times \frac{1}{2}$ . We will break down the steps involved in simplifying this expression and provide a clear explanation of each step.

Understanding the Problem

The given expression is a product of three fractions: $\frac{3}{5}$ , $\frac{10}{12}$ , and $\frac{1}{2}$ . To simplify this expression, we need to multiply these fractions together. However, before we do that, let's take a closer look at each fraction and identify any common factors that can be canceled out.

Step 1: Identify Common Factors

The first fraction is $\frac{3}{5}$ . The second fraction is $\frac{10}{12}$ . The third fraction is $\frac{1}{2}$ . To simplify the expression, we need to identify any common factors between the numerators and denominators of these fractions.

Common Factors in Numerators

The numerators of the fractions are 3, 10, and 1. We can see that there are no common factors between these numbers.

Common Factors in Denominators

The denominators of the fractions are 5, 12, and 2. We can see that the number 2 is a common factor between the denominators of the second and third fractions.

Step 2: Cancel Out Common Factors

Now that we have identified the common factors, we can cancel them out. The common factor of 2 in the denominators of the second and third fractions can be canceled out.

Simplified Expression

After canceling out the common factor of 2, the expression becomes:

$\frac{3}{5} \times \frac{10}{12} \times \frac{1}{1}$

Step 3: Multiply Numerators and Denominators

Now that we have simplified the expression, we can multiply the numerators and denominators together.

Multiplying Numerators

The numerators of the fractions are 3, 10, and 1. Multiplying these numbers together gives us:

$3 \times 10 \times 1 = 30$

Multiplying Denominators

The denominators of the fractions are 5, 12, and 1. Multiplying these numbers together gives us:

$5 \times 12 \times 1 = 60$

Simplified Expression

After multiplying the numerators and denominators together, the expression becomes:

$\frac{30}{60}$

Step 4: Simplify the Fraction

The fraction $\frac{30}{60}$ can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD of 30 and 60 is 30.

Simplified Fraction

After dividing both the numerator and denominator by 30, the fraction becomes:

$\frac{1}{2}$

Conclusion

In this article, we have simplified the complex fraction $\frac{3}{5} \times \frac{10}{12} \times \frac{1}{2}$ by identifying common factors, canceling them out, multiplying the numerators and denominators together, and simplifying the resulting fraction. The final answer is $\frac{1}{2}$ .
