2) Solve the following: Marks 2 x 5 = 10

A) Add the fractions 1/2 + 1/2

Answer:     ___1+1__________ = 2/2 = 1

                         2

 

B) Draw the angle 60 with the help of protractor.

 

 

C) Find the perimeter of the following:

 


Perimeter of this figure is summation of all sides: Therefore perimeter is: 1 + 1+ 1+ 1+1 + 1 = 6 cm ( There are six sides of the figure)


D) Find the missing length





Perimeter = 15
If we add all sides we get = 4 + 3 + 2 + ? = 15 cm = Perimeter
Therefore ? = 15 -4 -3 -2 = 6 cm
There fore Missing Length = 6 cm




E) Find the LCM of 12, 36, 24



2| 12, 36, 24
2|  6, 18,  12
2|  3,  9,    6
2|  3, 9,     3
3 | 1, 3,     1
3 | 1,  1,    1

Therefore LCM is 2 x 2 x 2 x 2 x 3 x 3 = 144
