1.	What is 1/3 of each of the collections given below?(1) 15 pencils (2) 21 balloons (3) 9 children (4) 18 books
Answer» i) One third of 15 pencils is: 1/3 x 15 = 1 x 5 = 5 pencils ii) One third of 21 balloons is: 1/3 x 21 = 1 x 7 = 7 balloons iii) One third of 9 children is: 1/3 x 9 = 1 x 3 = 3 children iv) One third of 18 books is: 1/3 x 18 = 1 x 6 = 6 books (1) 15 pencils → \(\frac{1}{3}\) of 15 = 5, 15 ÷ 3 = 5 pencils. (2) 21 baloons → \(\frac{1}{3}\) of 21 = 7,21 ÷ 3 = 7 baloons. (3) 9 children → \(\frac{1}{3}\) of 9 = 3, 9 ÷ 3 = 3 children. (4) 18 books → \(\frac{1}{3}\) of 18 = 6, 18 ÷ 3 = 6 books.

What is 1/3 of each of the collections given below?(1) 15 pencils (2) 21 balloons (3) 9 children (4) 18 books

Answer»

i) One third of 15 pencils is:

1/3 x 15

= 1 x 5

= 5 pencils

ii) One third of 21 balloons is:

1/3 x 21

= 1 x 7

= 7 balloons

iii) One third of 9 children is:

1/3 x 9

= 1 x 3

= 3 children

iv) One third of 18 books is:

1/3 x 18

= 1 x 6

= 6 books

(1) 15 pencils → \(\frac{1}{3}\) of 15 = 5, 15 ÷ 3 = 5 pencils.

(2) 21 baloons → \(\frac{1}{3}\) of 21 = 7,21 ÷ 3 = 7 baloons.

(3) 9 children → \(\frac{1}{3}\) of 9 = 3, 9 ÷ 3 = 3 children.

(4) 18 books → \(\frac{1}{3}\) of 18 = 6, 18 ÷ 3 = 6 books.
