Step-by-step solution

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

  • Step 1: Identify the given fractions.
  • Step 2: Take the reciprocal of the second fraction.
  • Step 3: Perform the multiplication using the reciprocal.
  • Step 4: Simplify the resultant fraction if possible.
  • Step 5: Convert to a mixed number if needed.

First, let's restate the problem equation:
We are to compute 56÷35 \frac{5}{6} \div \frac{3}{5} .

Step 1: Identify the fractions: 56 and 35 \frac{5}{6} \text{ and } \frac{3}{5} .

Step 2: Take the reciprocal of 35 \frac{3}{5} , which is 53 \frac{5}{3} .

Step 3: Multiply 56 \frac{5}{6} by 53 \frac{5}{3} :
56×53=5×56×3=2518\frac{5}{6} \times \frac{5}{3} = \frac{5 \times 5}{6 \times 3} = \frac{25}{18}.

Step 4: Convert 2518\frac{25}{18} to a mixed number:
25÷18=125 \div 18 = 1 remainder 77. Therefore, 2518=1718\frac{25}{18} = 1\frac{7}{18}.

Therefore, the result of 56÷35 \frac{5}{6} \div \frac{3}{5} is 1718 1\frac{7}{18} .

Final Answer

1718 1\frac{7}{18}

Key Points to Remember

Essential concepts to master this topic
  • Division Rule: Multiply by the reciprocal of the second fraction
  • Technique: 56÷35=56×53=2518 \frac{5}{6} \div \frac{3}{5} = \frac{5}{6} \times \frac{5}{3} = \frac{25}{18}
  • Check: Convert 2518 \frac{25}{18} to mixed number: 25 ÷ 18 = 1 remainder 7 ✓

Common Mistakes

Avoid these frequent errors
  • Dividing straight across without reciprocal
    Don't divide 56÷35 \frac{5}{6} ÷ \frac{3}{5} by doing 5÷36÷5 \frac{5÷3}{6÷5} = wrong answer! Division doesn't work like multiplication. Always flip the second fraction first, then multiply.

FAQ

Everything you need to know about this question

Why do I flip the second fraction?

+

Dividing by a fraction means "how many groups of that size fit into the first amount?" Flipping and multiplying gives you the same result as division, but it's much easier to calculate!

How do I know which fraction to flip?

+

Always flip the second fraction - the one after the division sign. In 56÷35 \frac{5}{6} ÷ \frac{3}{5} , flip 35 \frac{3}{5} to get 53 \frac{5}{3} .

Do I have to convert to a mixed number?

+

It depends on what the question asks for! If the answer choices are mixed numbers (like 1718 1\frac{7}{18} ), then yes. Otherwise, an improper fraction like 2518 \frac{25}{18} is perfectly correct.

How do I convert an improper fraction to mixed number?

+

Divide the numerator by denominator: 2518 \frac{25}{18} means 25 ÷ 18 = 1 remainder 7, so the answer is 1718 1\frac{7}{18} .

Can I simplify the fraction before converting?

+

Yes! Always check if you can simplify first. In this problem, 2518 \frac{25}{18} can't be simplified because 25 and 18 share no common factors besides 1.
