Answer:

20 Blue Buttons

8 Red Buttons

12 Green Buttons

Step-by-step explanation:

There are 40 buttons in a pack

50% are Blue so

40 × 50%

Change 50% to decimal

50% = 0.50

40 × 0.50 = 20

20% are Red so

40 × 20%

Change 20% to decimal

20% = 0.20

40 × 0.20 = 8

The rest are Green so

20 Blue buttons + 8 Red buttons = 28

40 - 28 = 12 Green buttons
