Question

The decimal 0.3 represents 1/3. What type of number best describes 0.9, which is 3 times 0.3? Explain.

Answer 1

it can be described as 9/10

Answer 2

`0.9=(9)/(10)`

Explanation:

We are given that decimal number 0.3 represents
`(1)/(3)`

We have to fine the number that describes best 0.9 and 3 times of 0.3

We are given that the number which descries best 0.9 is 3 times of 0.3

`0.3=(1)/(3)`

`0.9=(9)/(10)`

`0.3=(3)/(10)`

Multiply by 3 then we get

`0.3* 3=(3)/(10)* 3`

`0.9=(9)/(10)`

Hence, the number is
`(9)/(10)` which describes best 0.9.
