Answer:
A
Step-by-step explanation:
2/8 *1/7
Multiply the numerators together.
(2)(1)=2
Multiply the denominators together.
(8)(7)=56
2/56 - reduce
divide by 2 for the numerator and denominator
2/2=1
56/2=28
2/8 *1/7= 1/28 ( Answer)
Answer:
C
Step-by-step explanation:
factorizing 24:
factors of 24 : 1, 2, 3, 4, 6, 8, 12
looking at your answer choices, we can see that 5 and 7 are not factors of 24, so we can immediately eliminate a and b.
we also see that answer c does indeed contain factors of 24 and they both add to 10. So c is the answer.
8 divided by 24 = 0.33
8 divided by 3 = 2.6
24 divided by 8 = 3
24 divided by 3 = 8
This is a poorly described problem because books are different lengths meaning they possess different number of pages.
With that being said let's assume all books have exactly the same number of pages.
The formula to calculate how many books can he read in 12 days it's obvious:
![\frac{3}{4}\times12](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%5Ctimes12)
which is
![\frac{3\times12}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Ctimes12%7D%7B4%7D)
and then
![\frac{36}{4}=\boxed{9}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B4%7D%3D%5Cboxed%7B9%7D)
. Hope this helps!
