Answer 1

Answer: 6.4

Step-by-step explanation: its 6.4 because 640 divided by 100 is 6.4, and if they're all proportional than this is true for all of them.

Answer 2

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by,

`k=(y)/(x)`

So here, we have,

`k=(160)/(25)=(320)/(50)=(480)/(75)=(640)/(100)=6.4`

Thus, the constant of proportionality is 6.4.
