Question

To make punch, Sam mixes 3 liters of lemon soda with 2,800 milliliters of orange juice. How many liters of punch does this make?

Answer 1

I believe it's 6 liters.

Answer 2

Thanks

Answer 3

1000 mL = 1 L
2800 mL = 2.8 L

3 L + 2800 mL = 3 L + 2.8 L = 5.8 L

Answer 4

so it's 6 liters?

Answer 5

because of round up?

Answer 6

If you need to take significant figures into account,, then you would have to round the answer to 6 L.
Since 3 L has one significant figure and 2800 mL has 2, in an addition, the result has to have the lowest number of significant digits of all the numbers being added together.
