Solve: 4 × 3⅞ Mixed Number Multiplication Problem

To solve this problem, we'll follow these steps:

• Step 1: Convert the mixed number $3\frac{7}{9}$ to an improper fraction.
• Step 2: Multiply the improper fraction by the whole number 4.
• Step 3: Simplify the result back to a mixed number.

Now, let's work through each step:
Step 1: Convert $3\frac{7}{9}$ to an improper fraction:
The denominator is 9. Multiply the whole number 3 by 9 and add the numerator 7:
$3 \times 9 + 7 = 27 + 7 = 34$.
So, $3\frac{7}{9} = \frac{34}{9}$.

Step 2: Multiply $\frac{34}{9}$ by 4:
$4 \times \frac{34}{9} = \frac{4 \times 34}{9} = \frac{136}{9}$.

Step 3: Simplify $\frac{136}{9}$ to a mixed number:
Divide 136 by 9. The quotient is 15, and the remainder is 1. Thus, $\frac{136}{9} = 15\frac{1}{9}$.

Therefore, the solution to the problem is $15\frac{1}{9}$.
