Answer:
[tex]5\ liters\ 420\ ml[/tex]
Step-by-step explanation:
we know that
To find out how much water is needed to fill the tank completely, subtract 4,130 milliliters from 9 liters and 550 milliliters.
step 1
Convert to milliliters
Remember that
[tex]1\ liter=1,000\ ml[/tex]
so
[tex]9\ liters\ 550\ ml=9*1,000+550=9,550\ ml[/tex]
step 2
Find the difference
[tex]9,550\ ml-4,130\ ml=5,420\ ml[/tex]
step 3
Convert to liters and milliliters
[tex]5,420\ ml=5,000+420=5\ liters\ 420\ ml[/tex]
