Answer: the weight of each bags are 1.85kg,
1.85kg and 3.05 kg
Step-by-step explanation:
Total weight of the three bags is
6 3/4 kg. Converting to decimal, it becomes 6.75
kg.
Two of them have the same weight. Let X
represent the bags of equal weight. Their total
weight would be 2x. The third bag is heavier
than each of the bags of equal weight by 1 1/5
kg. Converting to decimal, it becomes 1.2kg. It
means that the weight of the third bag would be
x + 1.2
Therefore, for the three bags,
2x + × + 1.2 = 6.75
3x = 6.75 - 1.2 = 5.55
x=5.55/3=1.85
Weight of the third bag is
1.85+1.2=3.05kg
1.85kg and 3.05 kg
Step-by-step explanation:
Total weight of the three bags is
6 3/4 kg. Converting to decimal, it becomes 6.75

Therefore, for the three bags,
2x + × + 1.2 = 6.75
3x = 6.75 - 1.2 = 5.55
x=5.55/3=1.85
Weight of the third bag is
1.85+1.2=3.05kg
Answer:
lighter bag weighs 1 [tex]\frac{83}{100}[/tex]
heavier bag weighs 3 [tex]\frac{3}{100}[/tex]
Step-by-step explanation:
let x = weight of lighter bag
let x+6/5 = weight of heavier bag
2x + x+6/5 = 6 3/4
3x + 6/5 = 27/4
3x = 27/4 - 6/5
3x = 111/20
x = 111/20 ÷ 3
x = 1 83/100
x+ 6/5 = 3 3/100
