Question

Can someone show me steps to solve 120' 3 1/2" - 7"

Answer 1

keeping in mind that there are 12 inches in 1 foot, therefore 120' is 120*12 inches, namely 1440".

so, 120' 3½" is really just 1440" + 3" + ½", or 1443½".

then if we just subtract 7" from that, we end up with 1436½".

and we can convert that to feet by simply dividing it by 12, which gives us
`\bf 119(17)/(24)'`.
