160 x 4 =? ~a~
~b~ solve the equation i gave you
Answer
(3,1)
Explanation
(6,2) is the same as (3,1) because the x value and y value are proportional, meaning you multiplied or divided both the x value and y value by the same number.
6 divided by 2 is 3.
2 divided by 2 is 1.
(1,3) doesn't work because the x value and y value are switched.
6 divided by 6 is 1.
2 divided by 6 is not 3.
(8,12) doesn't work because the x value and y value are switched... and it wouldn't work anyways.
6 divided by 3/4 is 8.
2 divided by 3/4 is not 2.
(12,8) doesn't work because the x value and y value aren't proportional.
12 divided by 2 is 6.
8 divided by 2 is not 6.
Therefore only (3,1) could be another ratio to (6,2).
8 is 7
9 is 0.666666666667
