Answer 1

It can be described as 9/10

Answer 2

Answer:

$0.9=\frac{9}{10}$

Step-by-step explanation:

We are given that decimal number 0.3 represents $\frac{1}{3}$

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

$0.3=\frac{1}{3}$

$0.9=\frac{9}{10}$

$0.3=\frac{3}{10}$

Multiply by 3 then we get

$0.3\times 3=\frac{3}{10}\times 3$

$0.9=\frac{9}{10}$

Hence, the number is $\frac{9}{10}$ which describes best  0.9.
