Yes, "20eth" is not a correct spelling. The correct way to write it would be "20 ETH," which stands for 20 units of the cryptocurrency Ethereum.
Not necessarily. Take it to a gunsmith to find out the correct caliber/gauge.
The expanded form of 57,021 is: 50,000 + 7,000 + 20 + 1
The correct way to write one out of five is as a fraction: ( \frac{1}{5} ). You can also express it in decimal form as 0.2 or as a percentage, which is 20%. In a written context, you could say "one-fifth."
20 gauge is larger
NO!!! A 12 gauge shotgun takes only 12 gauge shells. A 20 gauge shell would fall into the barrel and get stuck about half way to the muzzle. You would be in for a nasty surprise when you put a 12 gauge shell behind it and pulled the trigger!!!
20 year sounds better
12 gauge is thicker than 20 gauge. The lower the gauge, the thicker the sheet metal or wire.
a 20 gauge is a type of many shotguns but it is smaller than a 12 gauge but bigger that a 410. a 20 gauge is a good shotgun for all ages.

20 gauge is equel to 0.8mm
The barrel and receiver should have the same serial number.
