Question

Kanye drake 1.9 L of water today. Madison drank 1800 mL of water today. Manisha 7.5 cups of water a day. Who drank the most water today?

Answer 1

convert all to liters
1000 ml=1L
therefor
1800ml=1800/1000L=1.8L
1 cup=0.236L
multiply
7.5 times 0.236=1.77

we have 1.9, 1.8,1.77
1.9 is greatest so Kanye drank the most water today
