Express the following rational numbers as decimals

(i) Given rational number is  

Now we have to express this rational number in decimal form. So we will use the long division method 

Therefore $\frac{2}{3}=0.6666$

$\Rightarrow \frac{2}{3}=0 . \overline{6}$

Hence, $\frac{2}{3}=0 . \overline{6}$

(ii) Given rational number is  

Now we have to express this rational number into decimal form. So we will use long division method

Therefore, $\frac{4}{9}=0.444$

$\Rightarrow-\frac{4}{9}=-0 . \overline{4}$

Hence, $-\frac{4}{9}=-0 . \overline{4}$

(iii) Given rational number is  

Now we have to express this rational number into decimal form. So we will use long division method

Therefore $\frac{2}{15}=0.1333$

$\Rightarrow \frac{2}{15}=0.1 \overline{3}$

Hence, $-\frac{2}{15}-0.1 \overline{3}$

(iv) Given rational number is  

Now we have to express this rational number into decimal form. So we will use long division method

Therefore $\frac{22}{13}=1.692307 \ldots$

$\Rightarrow \frac{22}{13}=1 . \overline{692307}$

Hence, $-\frac{22}{13}=-1 . \overline{692307}$

(v) Given rational number is  

Now we have to express this rational number into decimal form. So we will use long division method

$\Rightarrow \frac{437}{999}=0 . \overline{437}$

Hence, $\frac{437}{999}=0 . \overline{437}$

(vi) Given rational number is  

Now we have to express this rational number into decimal form. So we will use long division method

Therefore $\frac{33}{26}=1.2 \overline{692307} \ldots$

Hence, $\frac{33}{26}=1.2 \overline{692307}$
