1. The problem asks if the pair (1, 5) is equivalent to the pair (2, 10). 2. To check equivalence of two pairs, we can compare their ratios: \(\frac{1}{5}\) and \(\frac{2}{10}\). 3. Calculate each ratio: \(\frac{1}{5} = 0.2\) \(\frac{2}{10} = 0.2\) 4. Since both ratios are equal, the pairs (1, 5) and (2, 10) are equivalent. 5. Therefore, the answer is yes, they are equivalent.
