Question

Courtney has a 1.75-liter pitcher filled with fruit punch. How many grams of punch are in the pitcher if one liter of punch weighs one kilogram?

Answer 1

Hi. This can be answered with a ratio. If 1 litre = 1 kilogram then 1.75 litres = unknown grams. So we know that there are 1000 grams in 1 kilogram so 1.75 litres would be 1750 grams. Its just a matter of cross multiplying.
