Answer 2

Okay so for this one we have to do some multiplication

Answer 3

ok

Answer 4

The original shows that 2/10 of the books are green
if we multiply both of these numbers by 7 we get
14/70 books are green books

Answer 5

ok

Answer 6

In the original bookcase there are 3/10 red books
if we multiply both the numerator and the denominator by 7
we will find that in the new book case there are 21/70 red books
Right?

Answer 7

So there will be 21 red books in the bookcase, right?

Answer 8

yes
