Answer: we have 2,200milliters, 1000milliters, 1800milliters.
Step-by-step explanation:
Step 1
1 Liter= 1000 millilitres
5 liters = 5000 millilitres
Step 2
Dividing 5000 ml in the ratio 11:5:9
First, we find the Total ratio = 11+5+9 = 25
Such that
First part = 11/25 x 5000 = 2,200milliters.
Second Part = 5/25 x 5000=1000milliters.
Third part =9/25 x 5000=1,800milliters.
