Jake's water bottle has a capacity of 1.43 L. What is the bottle's capacity in milliliters?
otez555 [7]

Answer:

1430 milliliters

Step-by-step explanation:

so basically all you have to remember is 1 liter is 1000 milliliters so just convert the 1 into 1000 then remember that any decimals in the tenths or hundreds place act like the hundred for the on thousand. So 1000 plus 400 plus 30 equal 1430 milliliters.
