Express the following in the form p/q , where p and q are integers and q ≠ 0 : 0.2

Solution:

Given, the number is 0.2

We have to express the number in p/q form.

Let x = 0.2

Multiply by 10 on both sides,

10x = 0.2(10)

10x = 2

x = 2/10

Therefore, x = 1/5

✦ Try This: Express the number 0.4 in p/q form.

Given, the number is 0.4

We have to express the number in p/q form.

Let x = 0.4

Multiply by 10 on both sides,

10x = 0.4(10)

10x = 4

x = 4/10

Therefore, x = 2/5
