You divide 30 by 0.8 to get that M to equal 40. 30/0.8=40.
m = 32/0.8 m = 320/8 m = 40 Rule: You see in my second step? You have to get rid of the decimal to make it a whole number. So keep on adding 0 to the 32 until you transform 0.8 to a whole number. Ionly added 0 once to 32 because I only have to move the decimal once to make 0.8 a whole number. Hi
