There are 11 1/4 kilos of sugar that the class packed.
Step-by-step explanation:
George Polya
George Polya (1887-1985) a Hungarian mathematician, who wrote a book that made almost any problem simpler in some way. He devise the Polya’s 4 steps process in solving a problem known as Understand, Plan, Solve, and Check (Look Back) written in his book “How to Solve it Quickly” that was published around 1945.
Polya’s Four Steps Process in Solving Problem.
Polya’s First Principle: Understand the problem
• Do you understand all the words in the problem?
• What are you asked to find or show?
• Can you restate the problem in your own words?
• Can you think of a picture or diagram that might help you understand the problem?
Polya’s Second Principle: Make a plan
Determine the operation to be used Write the number sentence. You can use strategies such like Guess and check, look for a pattern, make an orderly list draw a picture,eliminate possibilities, use a model, work backwards, Use a formula and more.
Polya’s Third Principle: Solve (Carry out the plan)
In general, all you need is care and patience, given that you have the necessary skills. Persist with the plan that you have chosen. If it continues not to work discard it and choose another. Don’t be misled, this is how mathematics is done, even by professionals. You need to Show the solution.
Polya’s Fourth Principle: Check (Look back)
Polya mentions that much can be gained by taking the time to reflect and look back at what you have done, what worked, and what didn’t. Doing this will enable you to predict what strategy to use to solve future problems. State your complete answer.
In checking I used division, you will just divide the product by the multiplier and if the quotient will be the same as the multiplicand the answer is correct. Remeber in looking back/checking just know the opposite of each operation.
Addition-Subtraction and vice versa
Multiplication-Division and vice versa
if you have any questions or clarifications regarding my answer, dont hesitate to ask it.
