If N is a positive integer, it must be either even or odd.
If N is odd, then N-1 will be even.
If N is even, then N-1 will be odd.
Either way, when you multiply n and n-1, one of those expressions is going to be an even number, and any number multiplied by an even number is an even number.
Hope this helps! :)

Answer:
4
Step-by-step explanation:
The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in the circle, to one directly across)
In this case, the radius is 2.
So, 2 x 2 = 4.
The diameter is 4.
Answer:
= 3041666667/1000000000

Work:
Write the decimal number as a fraction
(over 1)
3.041666667 = 3.041666667 / 1
Multiplying by 1 to eliminate 9 decimal places
we multiply top and bottom by 9 10's
Numerator (N)
N = 3.041666667 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 3041666667
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 1000000000
N / D = 3041666667 / 1000000000
Simplifying our fraction
= 3041666667/1000000000
= 3041666667/1000000000
