Answer:
20%
Step-by-step explanation:
65 and 78 are both multiples of 13. Divide both by 13, we get 5 and 6.
If we use 5 as our main value (100%), 6 would be 120% as adding 1 to the main number (5) increases it by 20%. So 6 is a 20% increase from 5.
:D
These are not proportional. In order for them to be proportional they need to be constant (sorry if i’m wrong about that) it can’t be proportional because of the extra .25 cents added to it causing it to not run through the origin.
