What is the Constant of Proportionality for this table?

• It is 15 because it is the greatest number.

• It is 1.25 because it is the constant number.

• It is 0.8 because they divided the numbers wrong. It should be 4 divided 5 = 0.8; then 8 divided 10 = 0.8; and 12 divided by 15 =0.8.

• There is no constant of proportionality in this table.

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.

• There is no constant of proportionality in this table.
