Using the principle of proportionality, the part of rice required for 1.5 parts of beans is 2.25 parts of beans.

Setting up a proportional relationship : :

1 part of beans = 1.5 parts of rice

1.5 parts of beans = r

Hence,

1 = 1.5

1.5 = r

We can cross multiply

r = 1.5 × 1.5

r = 2.25

Therefore, the parts of rice required for 1.5 parts of beans is 2.25 or 2 1/4 parts of rice.
