Word Problems on Multiplication of Fractions by Whole Numbers(pureboy01 Series)

  



Good day my pupils, in this post ill teach you how to solve word problems on fractions.The main basic pattern of this mathematics is application in real life.once you understand the real scope involved is comparing what is going on in our daily life.One thing we should understand is math is all about working through what we experience in day to day life.



Mathematics makes things easy us when you know how to calculate each formula given.But a lots have it difficult to understand what its means to work on any given question.Here, what i we will discourse is solving words problem on fractions that we need to view the question well before we put it in action,This meas , i you really want to understand my point,just read this post carefully before you take a step.



 Now, let look at some good example on word problems , lets goo...


Example 1

                                           n                      3

A rectangular object has a length of 16 ------- meters and a breadth of 48 meters. Find the are of the object.

                                                                   4



Solution


                        3

Length = 16------- metres

                     4



Breadth = 48


Area = Length  x   breadth




             3

= 16 --------  x    48

           4



     67        48

= ------- x  -------

     4          1




      67  x  48

=  -------------- square metres

      4   x  1



= 804 square metres



The above is a simple solution that says that a rectangle has a length of 16 .3/4 squater and breadth of 48.All what to do is to remember the formula to find the area of a rectangular shape. his can be in three ways and the are:



  L  X  B




  2( l + b)

  and

  l + b + l + b




Example 2

                                            1

(1) Abasiekeme bought  6------ trouser length of cloth at N 1 250 .00 per trouser.How much does it cost him?

                                              2



   Solution


1 trouser length costs  =  1 250.00



      1                                           1        1250 .00

6------- trouser length cost = 6------- x -------------

     2                                            2               1




    

       13         1250           

 = ------  x  ----------

         2           1



 8 125.00


The above example says that, if 1 per of trouser costs 1 250.00, how much will 6 and half length cost?




                                                1

(2) A bag of sugar weight 6 --------kg.What is the weight  of 12 such bags?

                                                3



Solution

1 bag of sugar weighs = 6 and 1/3 kg

         

                                               1            12

12 bags of such weighs = 6-------  x ---------

                                                3            1





     

          19        12

  = -------- x --------

          3           1




 = 19  x 4


 = 64kg






(3) If 1/4 of 480  articles are sold,how much are not sold



Solution


  1

------  of   480

  4




                                  1         480

Articles not sold = -------  x -------

                                   4          1



= 1 x 120


= 120





(3) A  man's salary is N 27000.He spent 1/6 of the salary on rent and 2/5 on food.How much has he left.


Solution

His salary = 27000


                                         1        27000

Money spent on rent = ------- x ---------

                                         6          1



                   = 1  x  4500


                   = 4500



        

                                          3        22500

Money spent on food = ------ x ---------

                                           5          1




                 = 3 x 4500


                 = 13500



Money left=  13500 + 4500


          = 27000 - 18000

         = 9000
