Step-by-step solution

To solve the problem of converting the fraction 5500\frac{5}{500} into a decimal, we'll employ the following approach:

  • Step 1: Simplify the fraction 5500\frac{5}{500}.
  • Step 2: Convert the simplified fraction to a decimal.
  • Step 3: Verify the result through division.

Let's work through each step:

Step 1: Simplify the fraction:

The fraction 5500\frac{5}{500} can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 5:
5÷5500÷5=1100\frac{5 \div 5}{500 \div 5} = \frac{1}{100}.

Step 2: Convert the simplified fraction to a decimal:

1100\frac{1}{100} is equivalent to 0.01 in decimal form.

Step 3: Verify the result by division:

Dividing 5 by 500 gives:

5÷500=0.015 \div 500 = 0.01.

The division confirms that the decimal conversion is correct.

Thus, the value of 5500\frac{5}{500} in decimal form is 0.01\mathbf{0.01}.

Final Answer

0.01

Key Points to Remember

Essential concepts to master this topic
  • Rule: Find GCD of numerator and denominator first
  • Technique: Divide both 5 and 500 by GCD of 5
  • Check: Verify 1100=0.01 \frac{1}{100} = 0.01 by division ✓

Common Mistakes

Avoid these frequent errors
  • Converting to decimal without simplifying first
    Don't divide 5 ÷ 500 directly = harder calculation! This makes the arithmetic more complex and increases chance of errors. Always simplify the fraction by finding the GCD first, then convert to decimal.

FAQ

Everything you need to know about this question

How do I find the greatest common divisor quickly?

+

Look for common factors in both numbers! Since 500 = 5 × 100, the GCD of 5 and 500 is clearly 5. For larger numbers, list factors or use the division method.

Why is it better to simplify before converting to decimal?

+

Simplified fractions like 1100 \frac{1}{100} are much easier to convert! You immediately see that 1100=0.01 \frac{1}{100} = 0.01 without any complex division.

What if I can't find the GCD easily?

+

Try dividing both numbers by small primes like 2, 3, 5. Keep dividing until no common factors remain. For 5 and 500, both divide by 5!

Is 0.01 the same as 1%?

+

Yes! 0.01 = 1% because percent means "per hundred." So 1100 \frac{1}{100} = 1 per 100 = 1%.

Can I leave my answer as a fraction instead?

+

Absolutely! 1100 \frac{1}{100} is a perfectly valid answer. However, if the question asks for a decimal like this one, make sure to convert it to 0.01.
