Question

Two dressers are placed side by side. One dresser is 3 feet 6 inches wide, and the other is 2 feet 10 inches wide. Together, how wide are they?Write your answer in feet and inches. Use a number less than 12 for inches.

Answer 1

Since the width of the first dress is 3 feet 6 inches

Since the width of the second dress is 2 feet 10 inches

We will add their widths by adding feet and inches

`\begin{gathered} 3ft+2ft=5ft \\ 6in\mathrm{}+10in\mathrm{}=16in\text{.} \end{gathered}`

The width of both is 5 feet 16 inches

Since 1 foot = 12 inches, then subtract 12 from 16 inches and add feet by 1

`\begin{gathered} 16in-12in=4in \\ 16in=1ft,4in \end{gathered}`

The width of the 2 dresses is

`5ft+16in=5ft+1ft+4in=6ft\text{ 4in}`

The answer is 6 feet 4 inches
