16 cannot become a decimal. only fractions can become decimals. 16 is a whole number. The closest you could get to a decimal would be 16.0
You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
It is: 10/16 = 5/8 which as a decimal is 0.625
16 3/10 as a decimal is 16.3.
If you mean 16/10 then it is 1.6 as a decimal
10/16 = 0.625 10/16 = 0.625 10/16 = 0.625 10/16 = 0.625
16 and 3/10 = 16.3
1.6 is a decimal. It is 16/10 as a fraction, 8/5 in simplest form.
0.625
(10)hex = (16)decimal
2 10/16 = 2.625
Well, that would be true if the first two numbers are in base=11 but the 10 is in base=10. (15)11 = decimal 16 (6)11 = decimal 6 (15)11 - (6)11 = (decimal 16) minus (decimal 6) = decimal 10 (*For the solution to the Poptropica riddle, see the related question below.)
16 and 3/10
The answer is 0.625. I don't know what the mistake is.
