Step-by-step solution

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

  • Step 1: Convert the division into a multiplication problem.
  • Step 2: Simplify the result, if necessary.

Now, let's work through each step:
Step 1: We need to divide 64 \frac{6}{4} by 2. We can represent this as:

64÷2=64×12 \frac{6}{4} \div 2 = \frac{6}{4} \times \frac{1}{2}

This converts the division into a multiplication problem by using the reciprocal of 2, which is 12 \frac{1}{2} .

Step 2: Multiply the fractions:

6×14×2=68 \frac{6 \times 1}{4 \times 2} = \frac{6}{8}

Step 3: Simplify the fraction 68 \frac{6}{8} :
To simplify 68 \frac{6}{8} , divide both the numerator and the denominator by their greatest common divisor, which is 2:

6÷28÷2=34 \frac{6 \div 2}{8 \div 2} = \frac{3}{4}

Therefore, the solution to the problem is 34 \frac{3}{4} .

Final Answer

34 \frac{3}{4}

Key Points to Remember

Essential concepts to master this topic
  • Division Rule: Dividing by a number equals multiplying by its reciprocal
  • Technique: Convert 64÷2 \frac{6}{4} \div 2 to 64×12=68 \frac{6}{4} \times \frac{1}{2} = \frac{6}{8}
  • Check: Simplify 68 \frac{6}{8} by dividing both parts by GCD of 2 = 34 \frac{3}{4}

Common Mistakes

Avoid these frequent errors
  • Dividing numerator and denominator separately by the whole number
    Don't divide 6 by 2 and 4 by 2 to get 32 \frac{3}{2} ! This treats division incorrectly and gives the wrong answer. Always convert division to multiplication using the reciprocal method.

FAQ

Everything you need to know about this question

Why do I flip the number when dividing fractions?

+

Dividing by a number is the same as multiplying by its reciprocal. Since 2 = 21 \frac{2}{1} , its reciprocal is 12 \frac{1}{2} . This makes the math much easier!

What's the reciprocal of a whole number like 2?

+

The reciprocal of any whole number is 1that number \frac{1}{\text{that number}} . So the reciprocal of 2 is 12 \frac{1}{2} , the reciprocal of 3 is 13 \frac{1}{3} , and so on.

Do I always need to simplify my final answer?

+

Yes! Always simplify fractions to their lowest terms. Find the Greatest Common Divisor (GCD) of the numerator and denominator, then divide both by it.

How do I find the GCD of 6 and 8?

+

List the factors: 6 has factors 1, 2, 3, 6 and 8 has factors 1, 2, 4, 8. The greatest common factor they share is 2, so GCD(6,8) = 2.

Can I check my answer somehow?

+

Yes! Multiply your answer by the divisor: 34×2=64 \frac{3}{4} \times 2 = \frac{6}{4} . If you get back to the original fraction, your answer is correct!
