What two equivalent ratios for 30 to 6

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.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
