Ratios are also fractions.

1:5 is the same as 1/5.

So, the question really is 1/5 = 6/what?

6/30 is the same as 1/5

So the missing number is 30.

Answer:

box = 30

Step-by-step explanation:

You could set this up very formally as a proportion. It would look like this.

1/5 = 6/x

Now all you have to do is cross multiiply.

1*x = 5 * 6

x = 30

So the answer that goes in the box is 30

Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"

The answer is 6

6 * 5 = 30

In higher math you are going to want to use the first method.
