What is problem-solving?
Problem-solving is defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.
Problem-solving starts with identifying the issue. For example, a trainer may need to figure out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.
Calculation:-
Quantity of water Olivia took = half a gallon i.e 0.5 gallons.
Quantity of water Olivia drank =0.75 of 0.5
∴ 75% of 0.5 gallons
= 75/100 × 0.5
= 0.375 gallons.
