Hi there!
There are many equivalent ratios for 30:6.
Step by step explanantion:
30:6 when in ratios numbers, you can decide to divide or multiply. I will multiply for this one. 30x2=60 and so that you multiply 2 with 6 also. 2x6 would be 12. 60:12 would be one of them.
For this one I would divide by two/2. Same strategy but dividing, 30 divide 2 would be 15 so we know that the first one is 15. Divide 6 with 2 which would be 3. So for dividing by 2, you’ll get 15:3.
The two equilvalent ratios for 30:6 can be 60:12 and 15:3.
