which one can be considered as proper fraction?

• $\frac{0}{3}$

• $\frac{4}{3}$

• $2\frac{5}{3}$

• none of them

which one is correct?

• $\frac{0}{4}$ is a natural number

• we can demonstrate any fraction as natural number

• we can demonstrate any natural number as a fraction

• $\frac{0}{4}$ is not a fraction

If  $a$  and  $b$  are negative integers then

•  $b-a$  is a positive integers 

•  $-a-b$  is a positive fraction

•  $a-b+1$  is a negative integer

•  $\left|a-b\right|=b-a$  

How many fraction do we have between 1 and 1.4?

• 4

• 40

• 22

• too many
