Example of the Problem of Implementation of Integrating Computational Operations of SMP Grade 7 Semester 1
Example Problem Implementation of Operation Counting Integers [1945909] The Basic Mathematical Formula has described you about Mixed Count Operation in mathematics to complete the material Here are given some examples of additional questions that are still related to numerical operations so that you can know more about how the application of the calculation operation to solve mathematical problems. Let's take a look at the examples of problems and explanations of the following mathematical operations:
Sample Problem and Discussion Application of Counting Operation of Integers
Sample Problem 1
[1945909] ]
A multi storey building consisting of 40 floors with 4 floors underground.The man was originally on the 5th floor, Rang that left him down 3 floors. Then he climbed another eight floors to meet his friend. So, what floor is that man now?
[1945909]
Discussion:
We use the assumption when the man goes up we use the plus sign (+) and if the man goes down we use minus (-), then the count operation becomes:
It can be concluded that the man is currently on the 10th floor.
Sample Problem 2
In the college admission exam, the assessment Used
If the answer is true then the value is 4
If the answer is wrong then its value is -1
The unanswered question is 0
Of the 100 questions given at the time of the exam , Mahmud only able to answer 80 questions only, after examined there are only 65 correct answers. So what was the value of Mahmud?
[1945907]
Discussion:
First specify First what is the correct number of questions and how many questions are wrong:
Questions answered = 80 questions
Problem is correct = 65
Problem is wrong = 80 - 65 = 15 questions
Unanswered questions = 100 - 80 = 20
Then the value obtained by Mahmud is:
Problem True = 65 x 4 =
Problem false = 15 x (-1) = -15
Question not answered = 20 x 0 = 0
260 + (-15) + 0 = 245
Then the value that Mahmud had in The exam is 245.
Example Problem 3
For 8 days, Mulia Jaya cooperative distributes 4kg of rice to each family head Flood victims in Suka Menanti village. The number of victims to be given is 112 families. So, what is the amount of rice that the cooperative has shared?
Discussion:
Known the number of days is 8, the amount of rice is 4kg and the number of family heads is 112. So much of the rice is distributed is:
8 x 4 x 112 = 3584
So the rice that has been distributed by Mulia Jaya's cooperative for 8 days is 3584 kilograms
[1945907]
Sample Problem 4
Pak Karim has 160 marbles, then He distributed the marbles to his 4 children. After that, each child pak karim buy more marbles as many as 40 grains. So what is the number of marbles belonging to each child Pak Karim?
Discussion:
Number of marbles pack Karim = 160
Shared to his 4 children, each child gained: 160: 4 = 40
] Each child buys more than 40 marbles, so the number of marbles each child has is:
40 + 40 = 80 grains of marbles.
The count operation is: 160: 40 + 40 = 80
So many posts that can be described about Example Problem Application of Operation Calculate Integrating SMP grade 7 Semester 1 . We are sorry if in the above explanation there is kesaahan in word writing or calculation. Hopefully with the example of the above problems can add insight and your ability in bringing math problems related to the operation of the count.
