Proportional Reasoning

Question

A toy boat has a scale of 1:40 to an actual boat. If the mast on the toy boat weighs 216 grams, how many metric tons does the actual boat's mast weigh? (1000 g = 1kg and 1000 kg =1 ton) 

Answer 1

The toy boat is scaled 1:40

 

assuming the toy boat and the real boat have the same material making the mast

the weights would also be scaled 1:40

 

216 g * 40 = 8640 g = 8.64 kg = 8.64 tons
