Hello!
"Increase" means to add. We must find out what 45% of 140 fluid ounces is, and to do that we must first convert the percentage to a decimal and then multiply it by the amount of fluid ounces.
I know, that's probably a lot to take in! :D
45% ÷ 100 = 0.45 as a decimal
0.45 × 140 = 63
Add this to the amount of fluid ounces:
140 + 63 = 203
Final Answer:
203 fluid ounces.
