What is the Constant of Proportionality for this table?
It is 4 because 12 ÷ 3 = 4; 36 ÷ 9 = 4; 88 ÷ 22 = 4; and 100÷ 25 = 4; so 4 is constant.
It is 4 because 4 x 3 = 12; 4 x 9 = 36; 4 x 22 = 88; and 4 x 25 = 100; so 4 is constant.
It is 0.25 because 3 ÷ 12 = 0.25; 9 ÷ 36 = 0.25; 22 ÷ 88 = 0.25; and 25 ÷ 100 = 0.25; so 0.25 is constant.
