What is 3/15 in a decimal
Damm [24]
Well, since 3/15 can be simplified to 1/5 by dividing the top and the bottom by 3, you would just need to find the decimal of 1/5 which is much more commonly recognized. it's .2 (becasue 1/10 would be .1 and 1/5=2/10 so .1x2=.2)

What is the rate of change (86, 124) (64, 113)
harkovskaia [24]
Hey there!

The rate of change for these two points would be m = 1/2. Subtract the two y points from each other and then the two x points from each other. Then you divide them. Or get a simplified fraction.

Hope this helped!
