2/3 of the books are Language books and 1/5 are Science books. What can you conclude from this statement?
There are less Language books than Science books
There are more Language books than Science books
They are equal in number
Can’t say anything

If the remaining books are of Mathematics, what is the fraction of those books?
1/15 b) 4/15 c) 2/15 d) 7/15

Answer 1

a) language

b) 2/15

Explanation:

For the first part, you can start by making the denominators same

you take the LCM of 3 and 5 which is 15

Language books are now 10/15 since you multiply the nominator and denominator by 5

While science books are 3/15

10/15 : 3/15 making it obvious that language books are more

if the remaining are math books then

total books - (language + science books) = math books

10/15 + 3/15 = 13/15 (non math books)

15/15 - 13/15 are math books making 2/15 of them math books
