3 0

Step-by-step explanation:

First break it down

42= 40 & 2

27= 20 & 7

  • Then times 40 & 20 to get 800
  • 20 x 2 to get 40
  • 40 x 7 to get 280
  • 7 x 2 to get 14

Now add them all together.

800 40 1080

+280 +14 + 54

---------- ------- ---------

1080 + 54 = 1134

Hello from MrBillDoesMath!

Answer:

Number marbles >= 5
