Step-by-step solution

To solve this problem, we need to compare the fractions 13 \frac{1}{3} and 69 \frac{6}{9} .

We'll follow these steps:

  • Step 1: Simplify the fraction 69 \frac{6}{9} .
  • Step 2: Compare it to 13 \frac{1}{3} .

Step 1:
The fraction 69 \frac{6}{9} can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3.
Thus, 69=6÷39÷3=23 \frac{6}{9} = \frac{6 \div 3}{9 \div 3} = \frac{2}{3} .

Step 2:
Now, we compare 13 \frac{1}{3} with the simplified form 23 \frac{2}{3} .
Since 13 \frac{1}{3} has a smaller numerator than 23 \frac{2}{3} while both have the same denominator, it is evident that 13 \frac{1}{3} is less than 23 \frac{2}{3} .

Therefore, the correct sign to place between 13 \frac{1}{3} and 69 \frac{6}{9} is < < .

Final Solution: The correct answer is 13<69 \frac{1}{3} < \frac{6}{9} .

< <

Key Points to Remember

Essential concepts to master this topic
  • Rule: Simplify fractions first to find their lowest terms
  • Technique: Find GCD to reduce: 69=6÷39÷3=23 \frac{6}{9} = \frac{6÷3}{9÷3} = \frac{2}{3}
  • Check: Compare same denominators directly: 13<23 \frac{1}{3} < \frac{2}{3} since 1 < 2 ✓

Common Mistakes

Avoid these frequent errors
  • Comparing fractions without simplifying first
    Don't compare 13 \frac{1}{3} to 69 \frac{6}{9} directly = confusion and wrong answers! Different denominators make comparison difficult. Always simplify fractions to lowest terms before comparing.

FAQ

Everything you need to know about this question

How do I know if a fraction can be simplified?

+

Look for common factors in the numerator and denominator. If both numbers can be divided by the same number (like 3 divides both 6 and 9), then you can simplify!

What if the fractions have different denominators after simplifying?

+

Convert them to have the same denominator by finding the LCD (Least Common Denominator). Then compare the numerators directly.

Can I convert to decimals instead?

+

Yes! 13=0.333... \frac{1}{3} = 0.333... and 69=23=0.666... \frac{6}{9} = \frac{2}{3} = 0.666... . Since 0.333 < 0.666, we get the same answer.

Why is simplifying fractions important?

+

Simplifying makes fractions easier to work with and compare. 23 \frac{2}{3} is much clearer than 69 \frac{6}{9} when comparing to 13 \frac{1}{3} !

What's the fastest way to find the GCD?

+

List the factors of both numbers and find the largest one they share. For 6 and 9: factors of 6 are 1,2,3,6 and factors of 9 are 1,3,9. The GCD is 3.
