Answer 1

Option D: 6:12 is correct answer.

Explanation:

We can find the simplest form of ratio to compare it with the given ratios.

According to given statement,

The ratio is:

`No.\ of\ Blue\ Paint\ Gallons: No.\ of\ red\ paint\ gallons\\2:4\\Simplifying\\1:2`

Now we will check if the given options can be simplified to 1:2

So,

Option A:

`8:12\\2:3`

Option B:

`8:24\\1:3`

Option C:

`3:5`

Option D:

`6:12\\1:2`

As we can see that 6:12 can be simplified to 1:2 which is same as 2:4 so it will make the same shade of purple.

Hence,

Option D: 6:12 is correct answer.
