A scale model of a human heart is 16 ft long. The scale is 32:1. How many inches long is the actual heart that the model represents

(2) Answers

Its 512 ft. Because you multiply 16 by 32 to get 512


The real model is 0.5 feet long. As 32 is a multiple of 16, 16 x 2 = 32, correct? The inverse operation for multiplication is division, so you must divide 16 by 2, go give you 0.5. Also, think about it rationally, it makes sense to be 0.5 feet long! You can then clarify with the maths.
