Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)

Well, let's multiply them!
8/3 * 9/7 = 72/21
8/3 x 9/4 = 72/12.
We know the one with the smallest denominator is larger if the numerator is the same. So that means
72/12 is larger.
Answer: B) -56i - 24
This is the same as -24 - 56i
=============================================
Explanation:
The 'i' refers to the imaginary number 
In other words, 
Squaring both sides gets us 
So,

The result is in the form a+bi where a = -24 is the real part and b = -56 is the imaginary part.
