Question

Find the number that makes the ratio equivalent to 1:98: ?

Answer 1

72

Step-by-step 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.
