Proofs are... well... just that. They are your proof for why a certain property works or what you did to show your work. So essentially, you just do math like normal, a proof is showing what you did and why it works.
Answer:
A). 55
Step-by-step explanation:
Number of Variegated Fritillaries for each year is
2009 = 7
2010= 95
2011= 63
The sum total of the samples= 7+95+63
The sum total of the samples= 165
Number of years= 3
The average= total/number of years
The average= 165/3
The average= 55
512/56 = total servings
The box has 9 full servings, but in total has 9.143 servings.

First, let's make the mixed fraction improper:
- (3 3/8)
- { [(8 · 3) + 3]/8}
- { [24 + 3]/8}
- {27/8}
- (3 3/8) - (7/8)
- (27/8) - (7/8)
as the denominators are equal, we operate only with the numerators
- 34/8 <em>simplifying</em>
<h2>- 17/4</h2>
0.07 is 7/100 in fraction form. 1.68 is 168/100 in fraction form. in division you get the reciprocal of the second term and multiply both of the fractions. 7/100 x 100/168 = (100's cancel out) 7/168 = 1/24 when you simplify it
