Answer:
6/10 kg
Explanation:
Ed bought 4 pieces of salmon weighing a total of 2 kilograms. One piece weighed 4/10 kg, and two of the pieces weighed 5/10 kg each. What was the weight of the fourth piece of salmon? Explained
Hence:
Total kg of salmon = 4/10 + 5/10 + 5/10 + fourth piece
Total kg = 2 kg
Hence,
Fourth piece = 2 kg - ( 4/10 + 5/10 + 5/10) kg
Lowest common denominator = 10
2 kg - (4 + 5 + 5/10)
2kg - (14/10)kg
2 kg - 1 4/10 kg
= 6/10 kg
The weight of the fourth piece =
6/10 kg
