Example 3
Find 2/3 of 21
Solution:
First find 1/3 of 21, which is 21 ÷ 3 = 7
To get 2/3 of 21, we can get twice the i.e 7 +7= 14
or 2 x 7 = 14.
Therefore 2/3 of 21 = 14.
Example: 4
Solve ( 1/3 of 15) + ( 1/3 of 30)
Solution
To solve this, we need to solve each set of questions separately before solving them together.
(1/3 of 15) + ( 1/6 of 30)
1/3 of 15 = 5 , 1/6 of 30 = 5
5 + 5 = 1
Example 5
( 1/3 of 30) + ( 1/6 of 36)
10 + 6 = 16
Example 6
( 2/6 of 18) + ( 3/9 of 27)
6 + 9 = 15
