To divide by a fraction, multiply by its reciprocal. For example, \( \frac{2}{3} \div \frac{4}{27} = \frac{2}{3} \times \frac{27}{4} = \frac{54}{12} = \frac{9}{2} \).
Solución
It looks like the operation you need to perform involves dividing by the fraction \(\frac{4}{27}\). However, the first part of the operation (the dividend) seems to be missing from your question. To help you understand how to perform and simplify such operations, I'll provide a general explanation.
### **Dividing by a Fraction**
When you divide by a fraction, it's equivalent to multiplying by its **reciprocal**. The reciprocal of a fraction is created by swapping its numerator and denominator.
**General Rule:**
\[
a \div \frac{b}{c} = a \times \frac{c}{b}
\]
### **Step-by-Step Example**
Let's say you need to perform the following operation:
\[
\frac{2}{3} \div \frac{4}{27}
\]
**Step 1: Identify the Reciprocal of the Divisor**
The divisor here is \(\frac{4}{27}\), so its reciprocal is \(\frac{27}{4}\).
**Step 2: Multiply the Dividend by the Reciprocal of the Divisor**
\[
\frac{2}{3} \times \frac{27}{4}
\]
**Step 3: Multiply the Numerators and the Denominators**
\[
\frac{2 \times 27}{3 \times 4} = \frac{54}{12}
\]
**Step 4: Simplify the Fraction**
\[
\frac{54}{12} = \frac{9}{2} \quad \text{(by dividing both numerator and denominator by 6)}
\]
### **Final Answer**
\[
\frac{9}{2}
\]
### **Summary**
- **Divide by a fraction** by **multiplying by its reciprocal**.
- **Simplify** the resulting fraction if possible.
If you provide the complete operation, I'd be happy to help you solve it specifically!

The Deep Dive
To perform the operation \( 15 \div \frac{4}{27} \), you can multiply by the reciprocal of the fraction. This means you will multiply 15 by \( \frac{27}{4} \). So, the calculation becomes \( 15 \times \frac{27}{4} \). Now calculate it: \( 15 \times 27 = 405 \), and then divide by 4: \( 405 \div 4 = 101.25 \). You can leave it as is or express it as a fraction: \( 101 \frac{1}{4} \) or \( \frac{405}{4} \) in fraction form. The expression simplifies to \( 101.25 \).
