Question

A mechanic has a length of hose 3 ft long. What is length after 9 in is cut off? ( type your answer in standard form

Answer 1

for this case we know the total lenght of the hose 3ft

We cut off 9 in, we can convert this into ft on this way

`9in\cdot(1ft)/(12in)=0.75ft`

then the length after the cut off is:

3ft-0.75ft= 2.25 ft
