If there are 7 red cubes, 6 blue cubes, and 13 yellow cubes, what is the ratio red cubes to total cubes?

___ red: ____ total

well, how many total cubes are there?

How many red?

7 red and total 26 total

so, the ratio is 7:26

To find the ratio of red cubes to the total number of cubes, you need to add up the number of red, blue, and yellow cubes. Then, you can divide the number of red cubes by the total number of cubes.

In this case, there are 7 red cubes, 6 blue cubes, and 13 yellow cubes. To find the total number of cubes, you need to add these three quantities together: 7 + 6 + 13 = 26.

So, the total number of cubes is 26. The ratio of red cubes to the total cubes can be calculated by dividing the number of red cubes (7) by the total number of cubes (26).

Therefore, the ratio of red cubes to the total cubes is:
7 red : 26 total
