Question

Zoe has a board 5 1/4 long. she cut off a piece. now the board is 3 5/6 feet long. how long was the piece she cut off

Answer 1

The piece Zoe cut off would be 1 and 5/12 ft long.
5 and 1/4 - 3 and 5/6
The least common denominator is 24.
5 and 6/24 - 3 and 20/24
5 and 6/24 becomes 4 and 30/24
4 and 30/24 - 3 and 20/24 = 1 and 10/24
1 and 10/24 can be simplified to 1 and 5/12.

Answer 2

Answer:

length of piece cut off from the board was $1\frac{5}{12}$ feet.

Step-by-step explanation:

Board with Zoe has the length = $5\frac{1}{4}$ feet

≈ $\frac{21}{4}$ feet

Now she cut off a piece of length then the length of the board = $3\frac{5}{6}$ feet

≈ $\frac{23}{6}$ feet

Length of the piece of piece she cut off = $\frac{21}{4}-\frac{23}{6}$

= $\frac{63-46}{12}$

=  $\frac{17}{12}$

= $1\frac{5}{12}$ feet

Therefore, length of piece cut off from the board was $1\frac{5}{12}$ feet.
