Final answer:
Heidi had hair that was 1 1/3 meters long and she donated 5/6 of a meter. After subtracting the amount donated from her original hair length, we find that Heidi's hair is now approximately 0.5 meters long.
Step-by-step explanation:
Heidi originally had hair that was 1 1/3 meters long. She then donated hair that was 5/6 of a meter long. To determine how long Heidi's hair is now, we subtract the amount she donated from her original hair length.
1 1/3 meters is equivalent to 4/3 meters and 5/6 meters is equivalent to 0.833 meters.
When you subtract 0.833 meters (the hair that Heidi donated) from 4/3 meters (Heidi's original hair length), you find that Heidi's hair is now approximately 0.5 meters long.
