((-8 2/5)/(-4 1/10))*(-1/2)
(-(8*5+2)/5)/(-(4*10+1)/10)*(-1/2)
(-(42/5))/(-(41/10))*(-1/2)
((42/5)/(41/10))*(-1/2)
((42/5)*(10/41))*(-1/2)
((42*10)/(5*41))*(-1/2)
((420)/(205))*(-1/2)
(84/41)*(-1/2)
-((84*1)/(41*2))
-((84)/(82))
=-(42/41)

Jackie is reading a 252 page novel for her summer reading project. On Monday she reads 4/8 of the novel. On Tuesday she reads 28
natima [27]

So far, Jackie has read 217 pages

In order to determine the total number of pages Jackie read, we would have to determine the number of pages she read each day and add these pages together

  • Number of pages she read on Monday = \frac{4}{8} x 252 = 126 pages
  • Number of pages she read on Tuesday = 28 pages
  • Number of pages she read on Wednesday = \frac{1}{4} x 252 = 63 pages

The total number of pages she has read so far = 126 + 28 + 63 = 217 pages

Bob and mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
pychu [463]
I can only give possible combination of the ages. Had the sum of the ages been given, then the 3 specific numbers would have been derived.

We need to do prime factorization of 72.

72 ÷ 2 = 36
36 ÷ 2= 18
18 ÷ 2 =  9
  9 ÷ 3 =  3
  3 ÷ 1 = 1

1 x 2 x 2 x 2 x 3 x 3 = 72

Possible combinations:

1 x 8 x 9 = 72           1 + 8 + 9 = 18
1 x 4 x 18 = 72         1 + 4 + 18 = 23
2 x 4 x 9 = 72            2 + 4 + 9 = 15
3 x 4 x 6 = 72            3 + 4 + 6 = 13

The Ratio of boys to girls at a middle school is 3:2. If the school has 400 people how many will be boys?
Mekhanik [1.2K]
You have to divide 400 by 5. That will equal 80. Since the ratio is 3:2 Just multiply 3 by 80 then 2 by 80! :-) 

You can check it by simplifying it again.
