The product of r and 5 equals 197 how to turn it into an equation

r and 5 both make 197

r would be a use of a number that isn't known unless you rearrange the equation

The equation would be 5r = 197 or 5 x r = 197

So you could make r the subject,

And to find it, you could divide 197 by 5

197 / 5 = r

Which then would make r = 39.4
