Step-by-step solution

To find the result of dividing 24\frac{2}{4} by 43\frac{4}{3}, follow these steps:

  • Step 1: Simplify the fraction 24\frac{2}{4}. This becomes 12\frac{1}{2} because both the numerator and the denominator can be divided by 2.
  • Step 2: Find the reciprocal of the fraction 43\frac{4}{3}. The reciprocal is 34\frac{3}{4} because it exchanges the numerator and the denominator.
  • Step 3: Multiply 12\frac{1}{2} by 34\frac{3}{4}. 12×34=1×32×4=38 \frac{1}{2} \times \frac{3}{4} = \frac{1 \times 3}{2 \times 4} = \frac{3}{8}
  • Step 4: The result is 38\frac{3}{8}, which is already in its simplest form.

Therefore, the solution to the problem 24:43\frac{2}{4}:\frac{4}{3} is 38\frac{3}{8}.

Final Answer

38 \frac{3}{8}

Key Points to Remember

Essential concepts to master this topic
  • Rule: Division by a fraction means multiply by its reciprocal
  • Technique: 12×34=38 \frac{1}{2} \times \frac{3}{4} = \frac{3}{8} after finding reciprocal
  • Check: Verify 38×43=12 \frac{3}{8} \times \frac{4}{3} = \frac{1}{2} gives original dividend ✓

Common Mistakes

Avoid these frequent errors
  • Multiplying fractions directly without finding reciprocal
    Don't multiply 24×43=812 \frac{2}{4} \times \frac{4}{3} = \frac{8}{12} when dividing! This gives the wrong operation and wrong answer. Always flip the second fraction first, then multiply.

FAQ

Everything you need to know about this question

Why do I flip the second fraction when dividing?

+

Dividing by a fraction is the same as multiplying by its reciprocal. When you flip 43 \frac{4}{3} to get 34 \frac{3}{4} , you're converting division into multiplication!

Do I need to simplify before or after multiplying?

+

You can do either! In this problem, simplifying 24 \frac{2}{4} to 12 \frac{1}{2} first makes the multiplication easier, but the final answer will be the same.

What if my answer is an improper fraction?

+

That's perfectly normal! Just make sure to check if it can be simplified. In this case, 38 \frac{3}{8} is already in simplest form since 3 and 8 share no common factors.

How do I know if I did the division correctly?

+

Multiply your answer by the divisor: 38×43 \frac{3}{8} \times \frac{4}{3} . If you get the original dividend 12 \frac{1}{2} , you're correct!

Is there a shortcut for fraction division?

+

Remember the phrase "Keep, Change, Flip": Keep the first fraction, change ÷ to ×, and flip the second fraction. Then multiply across!
