In this article we are giving problem solving training and we can understand how to solving problems. It is very helping you to improve your problem solving skills. In mathematical terms we can see different types of problem solving. Here you can learn math terms, Exam practices test, problem solving and online test and our tutor will helps you and you can get free online tutor. Let us see Problem solving training.
Problem Solving:
Let us see few problems and their solving methods.
Problem solving training 1:
Solve: `12 / 6 + 5 / 3`
Solution:
Above problem is showing fraction addition. So we should solve this problem in fraction addition operation.
Step 1: `12 /6 + 5 / 3`
Here numerator values are same, but denominators are different. So we should take LCM then only we can add both values. (We can take LCM if denominators are different).
Step 2: `12 / 6 + 5 / 3`
Take LCM 6, 3 (therefore LCM is 6)
we have to change denominators values like 6.
Step 3: `(12*1)/(6*1) = 12/6 , (5*2)/ (3*2) = 10 / 6`
`12/6 + 10 / 6`
Now denominators are same so add both values
Step 4: `12 / 6 + 10 / 6`
`22 / 6`
Therefore `12/ 6 + 5 / 3 = 22 / 6.`
Problem solving training 2:
Solve: 20 ___ 5 = 25
Solution:
Step 1: Given 20 ___ 5 = 25.
Step2: here we find the symbols which are need for this operation.
Step 3: if we put the - (minus) symbols like 20 - 5 = 15 we can get 15.
So minus operation is not accept
Step4: + (plus) is correct operation for this problem.
20 + 5 = 25
Step 5: Therefore + (plus) symbol is making the number sentences true.
Problem solving training 3:
Divide the two fractions `40 -: 1/ 5`
Solution:
Above problem is showing fraction division. So we should solve this problem in fraction division operation.
Step 1: given` 40 -: 1/ 5`
Step 2: It denoted by `40 -: 1/5`
The right hand side denominator will be change like as 5/1 so
= `40 * 5/1`
= `200`
Step 3: Therefore answer is 200.
Practices Problems:
1) Solve this fraction `40/ 20` answer: 2
2) Add `2 / 3 + 3/ 2 ` answer: `13/6`
3) Find missing number 4 , 8 12 , ___ , 20 , 24 , ____ , 32 answer: 16 , 28
