The property for this case is to multiply both sides of an equation by a constant c * (2/5) * (1) = c * (40/100) The constant for this case is c = 5/2 Doing the multiplication we have (5/2) * (2/5) * (1) = (5/2) * (40/100) (5/5) * (2/2) * (1) = ((5) * (40)) / ((2) * (100)) (1) * (1) * (1) = (200) / (200) 1 = 1 Both sides of equality remain the same. answer The property for this case is to multiply both sides of an equation by a constant
