The correct Answer is:
To find the ratio A:C given the ratios A:B = 3:5 and B:C = 8:11, we can follow these steps: ### Step 1: Write down the given ratios We have: - A:B = 3:5 - B:C = 8:11 ### Step 2: Express the ratios in fractional form From the ratios, we can express them as: - A/B = 3/5 - B/C = 8/11 ### Step 3: Find A/C using the relationship of the ratios To find A:C, we can use the relationship: \[ A:C = A/B \times B/C \] Substituting the values we have: \[ A:C = \left(\frac{A}{B}\right) \times \left(\frac{B}{C}\right) = \left(\frac{3}{5}\right) \times \left(\frac{8}{11}\right) \] ### Step 4: Multiply the fractions Now we multiply the fractions: \[ A:C = \frac{3 \times 8}{5 \times 11} = \frac{24}{55} \] ### Step 5: Write the final ratio Thus, the ratio A:C can be expressed as: \[ A:C = 24:55 \] ### Final Answer The ratio A:C is 24:55. ---
