The sum of any one number is the value of that number.
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
Yes, the mean can be a decimal because the mean is a+b+c+d+(the numbers)....=e(the sum of the numbers), then e/(the quantity of numbers added together to get e)=f(the mean). Sometimes the sum may not go into the quantity in a whole number, which gives you a decimal.
It depends on your level of numerical skill. You can convert the decimal to an approximate fraction and estimate the sum of the two fractions, or you can convert the fraction to an approximate decimal and estimate the sum of the two decimals or, if you are more able you just estimate their sum directly.
No, the sum of a repeating decimal and a terminating decimal is never a terminating decimal.
