3 bottles contain 1.3l, 0.9l and 0.5l. Find the millilitres the mean average of these quantities

Answer 1

To find the mean average, you need to add up all the quantities and then divide by the number of quantities.

1.3l = 1300ml
0.9l = 900ml
0.5l = 500ml

Total = 1300ml + 900ml + 500ml = 2700ml

Now, divide the total by the number of quantities (3):

Mean average = 2700ml / 3 = 900ml

Therefore, the mean average of these quantities is 900 millilitres.
