Answer:
72
Explanation:
We can create equivalent ratios of 1:9 multiplying 1 and 9 by the same number. So, for example:
1:9 is equivalent to 3:27 because:
1 x 3 = 3
9 x 3 = 27
In the same way, we can create an equivalent ratio that starts by 8, multiplying both numbers by 8, so:
1 x 8 = 8
9 x 8 = 72
Therefore, the equivalent ratio to 1:9 is 8:72
So, the answer is 72.
