3. Group A after 1 second = 4.2
Group B after 1 second = 0.8

4.2 - 0.8 = 3.4

3.4 / 4.2 = 0.81

0.81 x 100 = 81%

Sadly not I take Biology, Chemistry and Geography
9. You do the percentage decrease which is 3.4 (4.2-0.8) then divide that by the original which is 4.2 then times by 100 and you get 81% (rounded up)
