Answer 2

Answer:

→ The decimal expansion of rational number is either terminating or non terminating repeating.

→If the denominator of rational number is of the form $2^a \text{or} 5^b \text{or} 2^a \times 5^b$ , then the decimal terminates.

   $\rightarrow -1 \frac{3}{4}=\frac{-7}{4}\\\\=-1.75$
