Question

the length of a pencil is 14 cm and diameter is 7mm. what is the ratio of the diameter to that of its length
​

Answer 1

Answer:

1:20

Step-by-step explanation:

The ratio of the diameter of the pencil to the the length of a pencil = 1 : 20

Explanation:

Given,

The length of a pencil = 14 cm = 140 mm and

[ ∵ 1 cm = 10 mm]

The diameter of a pencil = 7 mm

To find, the ratio of the diameter of the pencil to the the length of a pencil = ?

∴ The ratio of the diameter of the pencil to the the length of a pencil

= 7 mm : 140 mm

= 7 : 140

Divided by 7, we get,

=7/7:140/7

= 1 : 20

∴ The ratio of the diameter of the pencil to the the length of a pencil = 1 : 20
