By what process could you make a 'Tea-Table' into food?

I’m light as a feather, yet the strongest person can’t hold me for five minutes. What am I?

What number I am thinking of?

What is more useful when it is broken?

How many pluses should we put between the digits of 987654321 to get a total of 99, and where?

If,

20 % 5 = 24

21 % 7 = 33

42 % 6 = 67

Then;

66 % 6 = ?
