since the cross multiples are equal, you find a product and use the inverse operation as you would in an equation Example 4 is to 36 as 3 is to X: 4/36 = 3/X --> 4*X = 3*36. Divide both sides by 4, to solve for X = 27. is over of = percent of 100 is/of=%/100 What is 10% of 40. is = x x/40 = 10/100 cross mulitply 40*10= 400/100=4 x=4
4y = 2y + 40 4y - 2y = 2y -2y +40 2y = 40 y = 20 check 4(20) = 2(20) +40 80 = 80
