answer: an equation is a set of numbers put together within a problem that you are meant to solve in order to receive the final answer.
16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
Answer:

=> dy/dx = d/dx(
)
=> dy/dx = -
=> dy/dx = -1/
