You would multiply each kilogram amount by 2.2 to get the point equivalent.
The answer is 84 because of process priority
If you change the point's x-coordinate, the point will move either to the left or the right, depending on if the number you change is negative or positive.
We set up a proportion: 84/?= 56/100
Cross multiply: 56*?= 84*100
⇒ ?= 84*100/56= 150
56% of 150 is 84.
