Question

A factory makes sheets of metal that are 4 4/5 inches thick. if a worker at the factory makes a stack of 5 of the sheets, how many inches thick will the stack be? Simplify your answer and write it as a proper fraction or as a whole mixed number.

Answer 1

$24\:inches$

1) Since this factory produces sheets of metal 4 4/5 inches thick, we need to turn that mixed number into an improper one.

$4\frac{4}{5}=\frac{5\times4+4}{5}=\frac{24}{5}$

2) Now, we can multiply each sheet by five to get the height of the stack:

$\frac{24}{5}\times5=24\:inches$
