complete the tables so that the ratios are equivalent i don't understand

10 |
| 27
40 | 36
| 54
| 72

To find equivalent ratios, we need to make sure that the ratios compare the same relationship between the numerator and denominator.

In this case, the relationship between the numerator and denominator is not clear.

If we assume that the numerator and denominator are both multiplied by the same number to get the next number in each row, we can fill in the missing numbers:

10 * 3 = 30
30 * 3 = 90

40 * (9/5) = 72

We cannot determine the missing numbers on the left side of the second and third row, as there are an infinite number of possibilities that could create equivalent ratios. The provided numbers are not enough evidence to deduce the pattern for those rows.
