Multiply 3 × 1⅓: Mixed Number Arithmetic Solution

That approach can work, but it's more complicated! You'd get $3 \times 1 = 3$ and $3 \times \frac{1}{3} = 1$, then add: 3 + 1 = 4. Converting to improper fractions is more reliable.

Easy formula: Multiply the whole number by the denominator, then add the numerator. For $1\frac{1}{3}$: (1 × 3) + 1 = 4, so it becomes $\frac{4}{3}$.

No! When multiplying fractions, you don't need common denominators. Just multiply straight across: $3 \times \frac{4}{3} = \frac{3 \times 4}{3} = \frac{12}{3}$.

Always simplify your final answer! $\frac{12}{3} = 4$ because 12 ÷ 3 = 4. If it doesn't divide evenly, convert back to a mixed number.

Yes! Notice that $3 \times \frac{4}{3}$ has 3 in both numerator and denominator, so they cancel out, leaving just 4. Look for these cancellation opportunities!
