An empty jug weighs 0.80kg. It weighs 1.56kg when full.Work out the percentage difference.

Sure, here are the steps to calculate the percentage difference:

1. First, find the weight of the liquid in the jug by subtracting the weight of the empty jug from the weight of the full jug. So, 1.56 kg (full jug) - 0.80 kg (empty jug) = 0.76 kg (weight of the liquid).

2. Next, calculate the percentage difference. The formula for percentage difference is:

   (Difference / Original number) x 100%

   In this case, the original number is the weight of the empty jug (0.80 kg), and the difference is the weight of the liquid (0.76 kg). So, the calculation would be:

   (0.76 kg / 0.80 kg) x 100% = 95%

So, the percentage difference between the weight of the empty jug and the full jug is 95%.
