The intriguing expression "2 1 3 times 3 1 4" has been a subject of curiosity among math enthusiasts and puzzle solvers. At first glance, it appears to be a simple arithmetic operation, but upon closer inspection, it reveals itself to be a cleverly disguised mathematical challenge. As a mathematician with a passion for problem-solving, I will guide you through the process of unlocking the mystery behind this enigmatic expression.
The Expression "2 1 3 times 3 1 4" - A Mathematical Puzzle
The expression "2 1 3 times 3 1 4" seems to be a straightforward multiplication problem, but the use of spaces between the numbers suggests that there might be more to it than meets the eye. Let's break it down step by step to understand what's being asked. The expression can be interpreted as $2 \frac{1}{3} \times 3 \frac{1}{4}$.
Converting Mixed Numbers to Improper Fractions
To solve this problem, we need to convert the mixed numbers into improper fractions. A mixed number is a combination of a whole number and a fraction. To convert $2 \frac{1}{3}$ and $3 \frac{1}{4}$ into improper fractions, we use the following formulas:
- $2 \frac{1}{3} = \frac{(2 \times 3) + 1}{3} = \frac{7}{3}$
- $3 \frac{1}{4} = \frac{(3 \times 4) + 1}{4} = \frac{13}{4}$
Multiplying the Improper Fractions
Now that we have the improper fractions, we can proceed with the multiplication:
$\frac{7}{3} \times \frac{13}{4} = \frac{7 \times 13}{3 \times 4} = \frac{91}{12}$
Converting the Result back to a Mixed Number
To make the result more intuitive, let's convert the improper fraction $\frac{91}{12}$ back into a mixed number:
$\frac{91}{12} = 7 \frac{7}{12}$
| Mathematical Operation | Result |
|---|---|
| Conversion of $2 \frac{1}{3}$ to improper fraction | $\frac{7}{3}$ |
| Conversion of $3 \frac{1}{4}$ to improper fraction | $\frac{13}{4}$ |
| Multiplication of $\frac{7}{3}$ and $\frac{13}{4}$ | $\frac{91}{12}$ |
| Conversion of $\frac{91}{12}$ to mixed number | $7 \frac{7}{12}$ |
