Question

b) In one year, Clara and Dave borrowed books from a library in the ratio 3:7. Dave borrowed 35 books. Work out the number of books borrowed by Clara.​

Answer 1

I think it would be 15, because 3 doesn't go in evenly into 35. You might have the order of the ratio messed up.

Answer 2

3:7 =

3/7

3/7 = x/35

7x = 105

x = 15

answer : clara borrowed 15 books
