Question

An architect designs apartment buildings with the same ratio of small to large apartments. Building A has 12 small apartments and 6 large apartments. Building B has 18 small apartments.

Answer 1

9 large apartments in B

Explanation:

Same ratio

Building A = 12 small : 6 large

= 2 : 1

Building B = 18 small : x large

= 2 : 1

18/x = 2/ 1

18 = 2x

9 = x

Large apartments in B = 9
