Great question. The answer is N-1.
Think about doing long division. We append a 0, get another digit in the quotient, multiply and subtract to get a remainder. We can assume that remainder is not zero because then we wouldn't have a repeating decimal. At each step the remainder has to be less than N, because we're dividing by N.
So there are N-1 possibilities for the remainder. On the off chance we generate N-1 digits and N-1 remainders and none repeat, we know the next one will repeat, because we've already generated all the possible remainders.
So the largest size of the repeating portion is N-1. This maximum happens first for 1/7.
Answer:
-1
Step-by-step explanation:
slope = y2-y1/x2-x1
(5,5) (7,3)
slope = 5-3/5-7 = 2/-2 = -1
Answer:
<h2>(55/27, 32/9)</h2>
Step-by-step explanation:
The system of equations is
The first step is to arrange like terms in colums, which is already done.
Then, we need to multiply a number by one equation in such way where we get opposite like terms. Notice that we need to multiply the first equation by -1
Then, we sum equations to obtain the value of one variable.
Now, we use this value to find the second variable
Therefore, the solution is (55/27, 32/9).
