Hello, children. Today let's learn about decimals. First, you click the word - 
Decimals to start our lesson.


Now, you can try the exercise below to test if you understand the lesson.


Exercise


1)  42 - 6.75 + 3.221 - 6.51 =


2) 16.53 + 0.68 - 14.02 =


3)  18 - 6.45 - 1.8 = 46.73 - (        ) - (        )
     Calculating the total value of the two missing numbers.
4)  Add 24 to the difference of 314.464 and 19.20.


5)  P  =  2.65 - 0.821
     Q =  0.51 + 3.689
     P + Q =  ?


Now, you can check your answers here.


Answers:


1)  42.00 - 6.75 = 35.25
     35.25 + 3.221 = 38.471
     38.471 - 6.51 = 31.961


2)  16.53 + 0.68 = 17.21
     17.21 - 14.02 = 3.19


3)  18.00 - 6.45 = 11.55
     11.55 - 1.8 = 9.75
     46.73 - 9.75 = 36.98
     The total value of the two missing numbers is 36.98.


4)  314.464 - 19.20 = 295.264
     295.264 + 24 = 319.264


5)  P = 1.829
     Q = 4.199
     P + Q = 6.028


If you get all correct, well done! If you make some mistakes, make a greater effort. ^-^
