You can use the number line to help you with this problem:
A number line is shown. It starts at 0 and ends at 1. The number line is divided into eighths and each mark is labeled accordingly.
David marked a foot-long stick using eighths. If he breaks the stick at the 38 mark, then one piece is 38 of a foot long and the other piece is 58 of a foot long. This is represented by the equation 38+58=88 .
Use the equation editor to type two more equations that represent the stick being broken in different places.
(2 points)
1. If the stick is broken at the 1/3 mark, one piece is 1/3 of a foot long and the other piece is 2/3 of a foot long. This is represented by the equation 1/3 + 2/3 = 1.
2. If the stick is broken at the 1/2 mark, one piece is 1/2 of a foot long and the other piece is also 1/2 of a foot long. This is represented by the equation 1/2 + 1/2 = 1.
