Dozens of Nuts and Bolts Consider the same “reaction” above in terms of dozens of hardware pieces: B + 3N = BN3 One dozen bolts combines with three dozen nuts to make one dozen BN3.

Question

The answer to each should be “dozen.” These problems may be solved exactly as those above. The coefficients are simply scaled up to dozens.

5. How many dozen nuts (N) are needed to combine with 9 dozen bolts (B)?
6. How many dozen BN3 can be made from 56 dozen nuts (N)?
7. How many dozen B are needed to combine with 36 dozen N?
