Video Solution

Step-by-Step Solution

To solve the problem, let's proceed with the following steps:

  • Step 1: Convert the mixed number 2132 \frac{1}{3} to an improper fraction.
  • Step 2: Perform the multiplication with the whole number 2.
  • Step 3: Simplify and, if required, convert the result back to a mixed number.

Now, let's work through each step:

Step 1: Convert 2132 \frac{1}{3} to an Improper Fraction

The mixed number 2132 \frac{1}{3} can be converted to an improper fraction by multiplying the whole number 2 by the denominator 3 and adding the numerator 1. Thus, 213=2×3+13=6+13=732 \frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{6 + 1}{3} = \frac{7}{3}.

Step 2: Multiply by 2

Next, multiply the improper fraction 73\frac{7}{3} by the whole number 2. Treat 2 as 21\frac{2}{1} for multiplication: 73×21=7×23×1=143\frac{7}{3} \times \frac{2}{1} = \frac{7 \times 2}{3 \times 1} = \frac{14}{3}.

Step 3: Simplify or Convert the Improper Fraction

Finally, convert the improper fraction 143\frac{14}{3} back to a mixed number, if desired:

  • Divide the numerator by the denominator: 14÷3=414 \div 3 = 4 with a remainder of 2.
  • This results in the mixed number 4234\frac{2}{3}.

Therefore, the solution to the problem is 4234\frac{2}{3}.

Answer

423 4\frac{2}{3}
