if there's a question asking 3 5 15 25 21 [ ] 30 50 what would go under the 5 and the 25 when doing part-to-part ratios

To find the missing numbers in the pattern, we can determine the relationship between the given numbers and apply it to the missing numbers.

In this case, we can observe that the second number in each pair is always obtained by multiplying the first number by 5.

So, for the missing number under 5, we can calculate 5 * 5 = 25. Similarly, for the missing number under 25, we can calculate 25 * 5 = 125.
