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.
1) 14 + 34 = 1
2) 18 + 48 = 1
I think maybe
3/8 +,5/8 = 8/8 = 1
1/4 + 3/4 = 2/8 + 6/8 = 8/8 = 1
1/8 + 4/8 = 5/8 which is NOT 1
1/8 + 7/8 = 8/8 = 1
Those are correct. Here they are using the equation editor:
4) 3/8 + 5/8 = 8/8 = 1
5) 1/4 + 3/4 = 2/8 + 6/8 = 8/8 = 1
6) 1/8 + 4/8 = 5/8
7) 1/8 + 7/8 = 8/8 = 1
