I believe it's the first option. Hope this helps.
D because 5 times 2 is 10 and - cuts off - so -3 times -3 would be 9 so 10+9 is 19 :)
Your answer to your question should be B if not then i dont know
Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25
For this case we can rewrite the expressions as:
That is, we run the decimal three times to the left.
That is, we run the decimal six times to the left.
So:
So, we have that 
is 0.002996 times bigger than 
Answer:
