Explanation:
I'm going to use an example of 6:10 to explain this.
1. The factors of 6 are: 1, 2, 3, and 6.
2. The factors of 10 are: 1, 2, 5, and 10.
3. Then the greatest common factor of 6 and 10 is two.
4. Divide both terms by two.
5. 6 ÷ 2 = 3
6. 10 ÷ 2 = 3
7. Rewrite the ratio using the results. The simplified ratio is 3:5.
8. 6:10 is equal to 3:5 in simplest form.
I hope this helped! :)
