Diana has 1625 ml of orange juice in a jug. She poured the juice into similar glasses, filling each glass with 250 ml of orange juice. How much orange juice was left in the jug? Give answer in litres.
Diana poured 1625 / 250 = <<1625/250=6.5>>6.5 glasses of orange juice.
Since she used similar glasses, then multiplying the number of glasses with the volume of one glass would give the total volume of orange juice consumed which is: 6.5 x 250 = <<6.5*250=1625>>1625 ml.
Therefore, Diana had no orange juice left. Answer: 0 litres.
To find the amount of orange juice left in the jug, we need to determine how many glasses Diana filled.
First, we divide the total amount of orange juice in the jug, which is 1625 ml, by the amount of orange juice in each glass, which is 250 ml.
1625 ml ÷ 250 ml = 6.5
This means that Diana poured orange juice into 6.5 glasses.
Since we cannot have a fraction of a glass, we will round down to the nearest whole number, which is 6.
Therefore, Diana poured orange juice into 6 glasses, leaving some amount in the jug.
To find the amount left in the jug, we subtract the amount used in the glasses from the total amount.
1625 ml - (250 ml/glass × 6 glasses) = 1625 ml - 1500 ml = 125 ml
There is 125 ml of orange juice left in the jug.
To convert this to litres, we divide by 1000 (since there are 1000 ml in 1 litre):
125 ml ÷ 1000 = 0.125 litres
Therefore, there is 0.125 litres of orange juice left in the jug.
