Step-by-step solution

Let's proceed with solving the problem step by step:

  • Step 1: Convert the decimal 0.70.7 into a fraction.

    The number 0.70.7 can be expressed as a fraction by recognizing it as 710\frac{7}{10}, since the digit 77 is in the tenths place.

  • Step 2: Compare the two fractions, 7100\frac{7}{100} and 710\frac{7}{10}.

    Both fractions have the same numerator of 77. When comparing fractions with the same numerator, the fraction with the smaller denominator is the larger fraction. Thus, 710\frac{7}{10} is greater than 7100\frac{7}{100}.

  • Step 3: Determine the appropriate sign.

    Since 710\frac{7}{10} is greater than 7100\frac{7}{100}, we have: 7100<0.7\frac{7}{100} < 0.7.

The appropriate sign is therefore <<.

Therefore, the solution to the problem is that 7100<0.7\frac{7}{100} < 0.7.

Key Points to Remember

Essential concepts to master this topic
  • Rule: Convert decimals to fractions for easier comparison
  • Technique: 0.7 = 7/10, then compare 7/100 vs 7/10
  • Check: Same numerator means smaller denominator gives larger fraction ✓

Common Mistakes

Avoid these frequent errors
  • Assuming equal numerators mean equal fractions
    Don't think 7/100 equals 0.7 because both have 7 = wrong answer! The denominators are different (100 vs 10), making the fractions unequal. Always check both numerator AND denominator when comparing fractions.

FAQ

Everything you need to know about this question

How do I quickly convert 0.7 to a fraction?

+

Look at the decimal place! Since 7 is in the tenths place, write it as 710 \frac{7}{10} . The denominator matches the place value.

Why is 7/10 bigger than 7/100?

+

Think of pizza slices! 710 \frac{7}{10} means 7 pieces from a pizza cut into 10 slices (bigger pieces), while 7100 \frac{7}{100} means 7 pieces from a pizza cut into 100 slices (tiny pieces).

Can I just convert both to decimals instead?

+

Absolutely! Convert 7100=0.07 \frac{7}{100} = 0.07 , then compare 0.07 vs 0.7. Both methods work perfectly!

What if the fractions had different numerators too?

+

Find a common denominator first! Convert both fractions so they have the same bottom number, then compare the top numbers.

How can I remember which fraction is larger?

+

Use this trick: Same numerator, smaller denominator = larger fraction. It's like cutting the same amount into fewer pieces - each piece gets bigger!
