Ratio Comparison: Finding the Greatest Value
To determine the greatest ratio among the given options, we convert each ratio into a fraction and then calculate its decimal value. The ratio yielding the highest decimal value is the greatest.
Step 1: Convert Ratios to Fractions
The provided ratios can be expressed as fractions:
- $7:15 \implies \frac{7}{15}$
- $15:23 \implies \frac{15}{23}$
- $17:25 \implies \frac{17}{25}$
- $21:29 \implies \frac{21}{29}$
Step 2: Calculate Decimal Equivalents
Calculate the decimal value for each fraction:
- $\frac{7}{15} \approx 0.4667$
- $\frac{15}{23} \approx 0.6522$
- $\frac{17}{25} = 0.6800$
- $\frac{21}{29} \approx 0.7241$
Step 3: Compare Decimal Values
Comparing the calculated decimal values:
- $0.4667$
- $0.6522$
- $0.6800$
- $0.7241$
The largest decimal value obtained is approximately $0.7241$.
Step 4: Identify the Greatest Ratio
The decimal $0.7241$ corresponds to the fraction $\frac{21}{29}$. Therefore, the ratio $21:29$ is the greatest among the given options.
