Answer 1

Step-by-step explanation:

it's a question of proportion

39/4=x/6.5

39×4=x×6.5

156=x×6.5

x=156/6.5

x=24

so 24 books can be placed on the same shelf

Answer 2

Answer:

39 / 4 = x / 6.5

39 × 4 = x × 6.5

156 = x × 6.5

X = 156/ 6.5

X = 24

Ans) 24 books of thicknes 6.5 cm each

can be placed on the same shelf.
