Kelly drinks 0.5 liters of coffee and 0.3 liters of yogurt drink at breakfast. how much did she drink in total in milliliters?

800 milliliters

Step-by-step explanation:

we know that

To find out the total amount Kelly drank, add the amount of coffee and the amount of yogurt and convert the result to milliliters.

so

0.5+0.3=0.8 liters

Remember that

1 liter= 1,000 milliliters

so

0.8 liters=0.8*1,000=800 milliliters

i got 10.28 but that rounds up to 10.3
