tim,kara and ann are working together to write a 4page report each student are going to do an equal amount of writing. what fraction of entire report does each student need to write

Answers

Answer 1
Answer: Theres three people. So each person needs to do one third (1/3) of the report. 

The report is 4 pages long. So now calculate how much 1/3 of 4 is 

= 1/3 * 4 
= 4/3 
= 1 1/3 pages 

So each person needs to do one and a third pages. 

And if you think about it it makes sense. three people EACH doing one page (1 +1 +1 = 3 pages) and a third of a page (1/3 + 1/3 +1/3 = 1 page) = 4 pages (3 pages + 1 page)
Answer 2
Answer: Do 4/3 because there is 4 pages and you get 1.3, 1.3 is how much each person does and 1.3 is 1/3 of 4 so each person has to do a page and a third or 1/3 of the report

The formla of a midpoint of AB:

M\left((x_A+x_B)/(2),\ (y_A+y_B)/(2)\right)

We have A(-3, -7) and B(-1, 1). Substitute:

x_M=(-3+(-1))/(2)=(-4)/(2)=-2\n\ny_M=(-7+1)/(2)=(-6)/(2)=-3

Answer: M(-2, -3)
