To determine which two ratios are equivalent to 39, we first need to express 39 in terms of a fraction. The number 39 can be expressed as the ratio \( \frac{39}{1} \) or any equivalent ratio that represents the same value.
Now, let's analyze the given options to see which of them are equal to 39 or may reduce to it.
- 1/9 - This does not equal 39.
- 6/18 - This simplifies to \( \frac{1}{3} \), which does not equal 39.
- 1/3 - This does not equal 39.
- 6/9 - This simplifies to \( \frac{2}{3} \), which does not equal 39.
