Step-by-step solution

To solve this problem, we need to increase the fraction 110 \frac{1}{10} by a factor of 10. We will accomplish this by multiplying both the numerator and the denominator by 10.

  • Step 1: Multiply the numerator, 1, by the factor 10:
    1×10=10 1 \times 10 = 10
  • Step 2: Multiply the denominator, 10, by the factor 10:
    10×10=100 10 \times 10 = 100

The fraction 110 \frac{1}{10} , increased by a factor of 10, results in 10100 \frac{10}{100} .

After performing these steps, we have successfully increased the fraction by a factor of 10 to reach 10100 \frac{10}{100} .

The correct answer from the provided choices is: 10100 \frac{10}{100} .

Final Answer

10100 \frac{10}{100}

Key Points to Remember

Essential concepts to master this topic
  • Rule: Multiply both numerator and denominator by the same factor
  • Technique: Factor of 10 means 110×1010=10100 \frac{1}{10} \times \frac{10}{10} = \frac{10}{100}
  • Check: Verify 10100=110×10 \frac{10}{100} = \frac{1}{10} \times 10 by simplifying back ✓

Common Mistakes

Avoid these frequent errors
  • Multiplying only the numerator by the factor
    Don't multiply just the numerator by 10 to get 1010 \frac{10}{10} = wrong answer! This changes the fraction's value completely. Always multiply both numerator AND denominator by the same factor to maintain proportional scaling.

FAQ

Everything you need to know about this question

What does 'increase by a factor of 10' actually mean?

+

It means to make the fraction 10 times larger. Think of it as scaling up - like making a recipe 10 times bigger by multiplying every ingredient by 10!

Why do I multiply both the top and bottom numbers?

+

To keep the fraction proportional! If you only multiply the top, you change what the fraction represents. Multiplying both by the same number is like zooming in without changing the actual value relationship.

Is 10100 \frac{10}{100} the same as 110 \frac{1}{10} ?

+

No! 10100 \frac{10}{100} simplifies to 110 \frac{1}{10} , but it represents the scaled version. The question asks for the fraction after scaling, not the simplified form.

Could I just multiply 110×10 \frac{1}{10} \times 10 directly?

+

That would give you 1, not a fraction! When scaling by a factor, you multiply the entire fraction as 110×1010 \frac{1}{10} \times \frac{10}{10} to maintain the fractional form.

How can I check if my scaling is correct?

+

Convert both fractions to decimals: 110=0.1 \frac{1}{10} = 0.1 and 10100=0.1 \frac{10}{100} = 0.1 . Wait, that's not right! Actually, 10100=0.1 \frac{10}{100} = 0.1 but scaled means 10 times larger, so check: 0.1 × 10 = 1.0, and 10100 \frac{10}{100} represents the scaling process!
