A chocolate bar is cut exactly in half so that Alex and Sara can share. If Sara got a 3.4 cm long piece, what’s the length of the original chocolate bar?
- 3.4 cm
- 7 cm
- 6.8 cm
- 1.7 cm
Hint:
Form the equation using given information.
○ Solve the equation to get the answer.
The correct answer is: 6.8 cm
Step by step explanation:
○ Given:
A chocolate bar is cut exactly in half
Sara got a 3.4 cm long piece.
○ Step 1:
As chocolate was cut exactly in half so Alex and Sara will get equal length of piece.
∴ Alex also get 3.4 cm long piece.
○ Step 2:
○ Length of chocolate bar
length of chocolate bar = length of Alex’s piece + length of Sara’s piece
length of chocolate bar = 3.4 + 3.4
length of chocolate bar = 6.8 cm
Hence, the original length of the chocolate bar is 6.8 cm.
- Final Answer:
Correct option is
Option C. 6.8 cm.
