5 is to 8 as 15 is to (blank) ?

5/8 = 15/x

Cross multiply and solve for x.

5x = 120
x = 24

5 : 8 = 15 : 8

5/8 = 15/x
Cross multiply
5x = 270
x = ?

Should be

5 : 8 = 15 : x
5x = 120
x = ?

i still don't get the anwser but thanks anyway ! :)

To solve this analogy problem, we need to identify the relationship between the first pair of numbers and then find the corresponding number for the second pair.

In the first pair, 5 is related to 8 in some way. By comparing these numbers, we can see that 8 is larger than 5. Specifically, 8 is 3 more than 5.

Now, let's apply the same relationship to the second pair. If we add 3 to 15, we get 18. Therefore, 15 is to 18.

So, the answer to the analogy is 18.
