Step2247 [10]

Answer:

12

Step-by-step explanation:

When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that \frac{1}{10} is bigger than the fraction next to it so in order to find a fraction that is lesser in value than  \frac{1}{10}, we need to find a denominator that is <u>more than 10</u>, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.
