Answer

The equivalent ratios are \( \frac{20}{28} \), \( \frac{15}{21} \), and \( \frac{10}{14} \).

Solution

To find ratios equivalent to \( \frac{5}{7} \), we can multiply both the numerator and the denominator by the same number. Equivalent ratios maintain the same value as the original ratio. Here's how to identify them: 1. **Multiply by 3:** \[ \frac{5 \times 3}{7 \times 3} = \frac{15}{21} \] - **Equivalent Ratio:** \( \frac{15}{21} \) → **Option E** 2. **Multiply by 2:** \[ \frac{5 \times 2}{7 \times 2} = \frac{10}{14} \] - **Equivalent Ratio:** \( \frac{10}{14} \) → **Option H** 3. **Multiply by 4:** \[ \frac{5 \times 4}{7 \times 4} = \frac{20}{28} \] - **Equivalent Ratio:** \( \frac{20}{28} \) → **Option C** **Therefore, the three equivalent ratios are:** - **C.** \( \frac{20}{28} \) - **E.** \( \frac{15}{21} \) - **H.** \( \frac{10}{14} \)

To find equivalent ratios to \(\frac{5}{7}\), you can multiply both the numerator and denominator by the same non-zero number. For instance, multiplying by 3 gives \(\frac{15}{21}\), and multiplying by 2 gives \(\frac{10}{14}\). Among the options you listed, \(\frac{10}{21}\) (which is already in simplest terms as it is derived from multiplying by 2), \(\frac{15}{21}\) (which simplifies down to \(\frac{5}{7}\)), and \(\frac{10}{14}\) (which simplifies down to \(\frac{5}{7}\) as well) are all equivalent to the original ratio. So, acceptable equivalent ratios are: - \(\frac{10}{21}\) - \(\frac{15}{21}\) - \(\frac{10}{14}\) Remember, you want to ensure any ratio remains in proportion to the original!
