Kylie drank 35% ofna 400-ml contanier of water. eugenia drank 45% of a 350 ml container of water. who drank more? explain how you know.

Let Kylie's container (which is 400ml) be 100%. She drank 35%. Proportion:
400ml - 100%
x ml    - 35%
So Kylie drank:
x=(400*35)/100=140 ml of water

Whole Eugenia's container (350ml) is also 100% and she drank 45%.
350ml - 100%
xml     - 45%
Eugenia drank:
x=(350*45)/100=157,5ml of water

Thus, Eugenia drank (157,5-140)=17,5 ml more than Kylie

< i think this is the answer unless i did my math wrong
