(please show your work if you can :D)

Answer 1

Answer:

Step-by-step explanation:

Increase

Increase = $\dfrac{4}{5}-\dfrac{2}{5}=\dfrac{2}{5}$

Increase percentage = 2/5 out of 2/5 * 100

                                    $=\dfrac{2}{5}*\dfrac{5}{2}*100$

                                     = 100 %
