MONEY

CONVERT RM TO SEN

RM 5.30 = 530 sen ( move two decimal place )

1875 sen = RM 18.75 ( 1875 devide 100)


MIXED OPERATION INVOLVING MONEY

RM 18 - 245 sen + RM 5.70 = RM 21.25

      RM 18. 00
    - RM  2. 45 
      RM 15.55
   + RM   5.70
      RM 21.25

TIME

Convert unit of Time

1 hour = 60 minutes                                    1 minutes = 60 seconds
1 day = 24 hours
1 week = 7 days                                                        
1 year = 12 months 

1 decade = 10 years

1 century = 100 years

1 century = 10 decades

 

Convert 12 hours system to 24 hours system

       7 : 30 a.m =   0730 hours                                   3 : 45 p.m =  1545 hours
       9: 45 a.m  =  0945 hours
      10 : 50 a.m =  1050 hours                                       3  45
                                                                                 + 12  00
                                                                                     15 45 hours 

 

Convert 24 hours system to 12 hours system

        0920 hours =  9 : 20 a.m                                    2055 hours  =  8 :55 p.m
        1145 hours  =  11: 45 a.m
                                                                                             2055                                                                              
                                                                                         -   1200
                                                                                              8:55 p.m

PERCENTAGE ( TOPIC 4)

Example 1                                                 Example 2

17 % =  17                                               0.23 =   23   =   23 %
            100                                                           100


Example 3                                                Example 4

 25 %  =  25   =   1                                     3  x  20  =  60   =  60  %
              100        4                                    5   x  20     100
                                                                ( group of hundred )


Example 5                 Example  6                      Example  7

  40 % of  800           20 % of RM 500            30 % of 3.5 kg

=  40  x   800          =  20    x  RM 500            =  30  x  3500 g
   100                         100                                    100 

= 320                        = RM 100                       = 1050 g
