Answer:
The foreman's error was he divided 3 by 12 = 3 ÷ 12
The correct step would be to divide 12 by 3 = (12÷ 3)
Explanation:
The foreman's error was he divided 3 by 12 = 3 ÷ 12
A construction company uses 12 pieces of plywood to make 3 sheds. The foreman will be making 6 sheds next week.
Hence , the correct calculation is:
3 sheds = 12 pieces
1 shed = x
3 × x = 12 × 1
3x = 12
x = 12/3
x = 4 pieces
1 shed requires 4 pieces of plywood
The unit rate of how many pieces of plywood he uses per shed is 4 pieces per shed
Hence, the correct step would be to divide 12 by 3 = (12÷ 3)
The number of pieces required for 6 shed is 4 × 6 sheds
= 24 pieces of plywood
