How to Solve 4 Divided by 1 1/3: the Complete Beginner’s Guide
By David Miller
Once both numbers are formatted as clean fractions, standard elementary math operations take over. Fraction division relies on the keep change flip rule. You keep the first fraction unchanged, change the division sign to multiplication, and flip the second fraction into its reciprocal.
The reciprocal of a fraction simply swaps the positions of the numerator and denominator. When you flip 4/3 upside down, it turns into 3/4. The operation shifts from division to direct multiplication: (4/1) × (3/4).
Multiplying fractions requires multiplying straight across the top and bottom. Multiply the numerators: 4 × 3 = 12. Next, multiply the denominators: 1 × 4 = 4. This calculation yields the unreduced fraction 12/4.
The final phase requires fraction reduction. Dividing the numerator 12 by the denominator 4 gives an exact value of 3. Alternatively, you can cross-cancel before multiplying: the numerator 4 in 4/1 and the denominator 4 in 3/4 cancel out to 1, leaving 1 × 3 over 1 × 1. The result remains identical.
