Answer:

5/18

First, identify how many blue marbles there are (5). That's what the numerator (the top number on the fraction) is going to be. From there, take all the numbers given (5, 2, 6, and 5) and add them up (18). This is what you're goign to put as the denominator (the number on the bottom). Lastly, go and make sure that it can't be simplified at all (find the least common factor of the two if there is one.)

What is the remainder of 10^2017 divided by 1001?
pashok25 [27]
Note: When I use the double equal sign, I mean the triple bar used with modular arithmetic

10^3 = 1000 == -1 (mod 1001)
10^3 == -1 (mod 1001)
(10^3)^672 == (-1)^672 (mod 1001)
(10^(3*672) == 1 (mod 1001)
10^2016 == 1 (mod 1001)
10*10^2016 == 10*1 (mod 1001)
10^2017 == 10 (mod 1001)

Final Answer: 10
