Answer 2

It looks like you've provided a couple of mathematical equations involving ratios. Let's solve them step by step:

1. 15:3 = x:6

The ratio 15:3 can be simplified to 5:1 by dividing both numbers by their greatest common divisor, which is 3. Now we have:

5:1 = x:6

To find the value of x, we can set up a proportion:

5/1 = x/6

Cross-multiply:

5 * 6 = 1 * x 30 = x

So, the solution for the first equation is x = 30.

2. 26:2 = 39:2

This equation is already balanced, as both sides of the ratio are equal. The ratio is 13:1. In other words, 26 is 13 times greater than 2, and 39 is also 13 times greater than 2.

So, the solution for the second equation is 13:1.
