Because they don't matter!
It's kind of like the number e.g. 6
6=06=006=000000000000000006
It's all the same!
So
0.09=0.090000=0.090000000000000000000000000000

the 2 zeros at the end
Scientific notation is when you remove all the zeros from the number so you end up with 789. Then you put a decimal between the first and second numbers. After that you put a x10 then count all the zeros and put it to that power.
If it ends in a decimal, then it must be a whole number. Repeating could be ruled out immediately because even though theoretically it could be a thought of as a repeating decimal with infinite zeros repeating, adding zeros doesn't change the quantity and you could in theory add infinite zeros to the end of ANY decimal. That does not make it repeating.
The only way to make another decimal that's equivalent to 7.16 is to add zeros on the end of it. For example: 7.1600000
Remove the percentage sign.If there is a decimal point in the number move it two spaces to the leftotherwise, insert a decimal point two spaces from the end - inserting zeros as necessary.37.6% = 0.3767.6% = 0.07637% = 0.377% = 0.07
