The  fraction of the total books about mammals is 7/18

Let the total number of books in the school be 1 whole , ie 12/12( since we are dealing with fractions)

Number of science books =7/12

Number of mammals books =2/3 of science books

=2/3  x 7/12=14/36 = 7/18

Since the total books are 12/12 which is also =1 whole

Then the fraction of total books that are about mammals are 7/18 x 1 whole =7/18

You go shopping with your friends and buy a shirt for $10.50 how much tax do you have to pay?
raketka [301]

It depends on how much the tax is. You take however much tax it is, and make that number and turn it into a decimal, move it two to the right, and multiply your tax by $10.50. But you DON'T do anything to the $10.50.

Hoped this helped. :)

A = (-7.2) / (-8.1) / (-3.7) = Negative

B = (-7.2) / (8.1) / (3.7) = Negative

I need help with this logic puzzle,
natka813 [3]
I cannot reach a meaningful solution from the given information. To prove that S was always true, you would have to prove that N was always false. To prove that N was always false you would have to prove that L was always false. For the statement (L ^ T) -> K to be true, you only need K to be true, so L can be either true or false.
Therefore, because of the aforementioned knowledge, I do not believe that you can prove S to be true.
