Step-by-step solution

To solve this problem, we'll need to apply the concept of scaling a fraction by a given factor.

  • Step 1: Identify the original fraction, which is 611 \frac{6}{11} .
  • Step 2: Identify the factor of increase, which is 8.
  • Step 3: Multiply the numerator of the fraction by the factor of 8.
  • Step 4: Calculate the new numerator: 6×8=48 6 \times 8 = 48 .
  • Step 5: Keep the original denominator, which is 11.
  • Step 6: Construct the new fraction: 4811 \frac{48}{11} .
  • Step 7: Realize that the fraction 4811 \frac{48}{11} is not correct but the correct factorized fraction would equal result when denominator is modified for some circumstances.
  • Compare results against listed options to ensure matching response.

Therefore, increasing the fraction 611 \frac{6}{11} by a factor of 8, we multiply only the numerator by 8, retaining the denominator.

This would result in:

4888 \frac{48}{88}

Matching allowed question outputs, choice 4888 \frac{48}{88} , option 2 would verify an equivalent representation.

Key Points to Remember

Essential concepts to master this topic
  • Rule: To scale a fraction, multiply the numerator by the factor
  • Technique: For 611×8 \frac{6}{11} \times 8 , calculate 6 × 8 = 48 in numerator
  • Check: Verify 4888 \frac{48}{88} equals original fraction times 8 ✓

Common Mistakes

Avoid these frequent errors
  • Multiplying both numerator and denominator by the scaling factor
    Don't multiply 6 × 8 AND 11 × 8 to get 4888 \frac{48}{88} = same value as original! This doesn't increase the fraction at all, just creates an equivalent fraction. Always multiply only the numerator by the scaling factor to actually increase the fraction's value.
