00:04 Let's convert the fraction to a decimal.
00:07 First, change the fraction so its bottom number is a multiple of ten.
00:12 Multiply both the top and bottom numbers by the same amount.
00:21 Then, write the top number out as a whole number.
00:25 Now, move the decimal point left, based on the bottom number.
00:30 If there are three zeros, move it three places to the left.
00:34 And that's how we find the solution!

Step-by-step written solution

Follow each step carefully to understand the complete solution
1

Understand the problem

6500= ? \frac{6}{500}=\text{ ?}

2

Step-by-step solution

Let's first multiply both the numerator and denominator by 2 to make the denominaor 1000:

6×2500×2=121000 \frac{6\times2}{500\times2}=\frac{12}{1000}

Now let's rewrite the simple fraction as a decimal:

12.0 12.0

Since the fraction divides by 1000, we'll move the decimal point three places to the left:

.0120 .0120

Finally we can add a zero before the decimal point to get our answer:

0.0120=0.012 0.0120=0.012

Final Answer

0.012

Key Points to Remember

Essential concepts to master this topic
  • Rule: Convert to power-of-ten denominator for easy decimal placement
  • Technique: Multiply 6/500 by 2/2 to get 12/1000
  • Check: Verify 0.012 × 1000 = 12, then 12 ÷ 500 = 6 ✓

Common Mistakes

Avoid these frequent errors
  • Moving decimal point wrong direction
    Don't move the decimal right when dividing by 1000 = gets 12.000 instead of 0.012! Division by powers of ten moves decimal LEFT. Always count zeros in denominator and move decimal that many places left.

FAQ

Everything you need to know about this question

Why multiply by 2/2 instead of just dividing 6 by 500?

+

Multiplying by 2/2 converts the denominator to 1000, a power of ten! This makes decimal placement much easier since you just move the decimal point left by the number of zeros.

How do I know how many places to move the decimal?

+

Count the zeros in the power-of-ten denominator. For 1000, there are 3 zeros, so move the decimal point 3 places to the left.

What if I can't make the denominator a power of ten?

+

You can always use long division instead! Divide the numerator by the denominator: 6 ÷ 500 = 0.012. Both methods give the same answer.

Why does 121000 \frac{12}{1000} equal 0.012?

+

Think of it as 12 thousandths. Since 1000 = 10³, each unit is 0.001. So 12 × 0.001 = 0.012.

Can I simplify the fraction first?

+

Yes! 6500=3250 \frac{6}{500} = \frac{3}{250} after dividing by 2. But converting to a power-of-ten denominator is often easier for finding decimals.
