Explain how you would solve 16/c=8. Then solve the equation

16/c = 8

That means 16 divided by same random number "c" makes the number 8. This also means that 8 times that random number you divided by makes 16.

Using this, you can rearrange the equation in various ways.

16/c = 8

16 = c*8

c = 16/8

We only really need that last one, c = 16/8,

16/8 = 2

c = 2

16/c=8

16/c=8/1

cross multiple

16=8c

c=16/8

c=2
