How do you you do this please help me?
frosja888 [35]

The opposite of multiplication is division, so if you take the signaler number after the equal sign divide it by the number before and it will give you the missing number like this:

(I'm only going to do a few and then you try it. I can check it when you are done)

6 x ____ = 60 <<<Divide 6 by this number

60 ÷ 6 = 10

6 x 10 = 60

140 ÷ 10 = 14

140 = 14 x 10

500 ÷ 50 = 10

50 x 10 = 500

Hope this helps!
