if I have 1/2 liter of while and drink another 750 milliliters of water how many liters of water did I drink in all? I believe it is 1 and 1/4 is this correct?
Yes. That's right.
To find the total amount of water you drank, we need to combine the 1/2 liter and the additional 750 milliliters.
First, let's convert the 750 milliliters into liters. Since there are 1000 milliliters in one liter, we divide 750 by 1000:
750 milliliters ÷ 1000 = 0.75 liters
Now, add the 1/2 liter of water with the 0.75 liters of water:
1/2 liter + 0.75 liters = 0.5 liters + 0.75 liters = 1.25 liters
So, you are correct! You drank a total of 1 and 1/4 liters of water.
