Answer 2

Answer:

The repeating decimal number is $-\frac{2}{3}=-0.666.....$

Step-by-step explanation:

Given : Numbers $-\frac{2}{3}, -\frac{3}{5}, \frac{3}{10}, \frac{11}{20}$

To find : Which number below represents a repeating decimal ?

Solution :

To determine the repeating decimal we have to solve each fraction,

i.e. divide denominator by numerator if we get the reminder 0 it is terminating but if remainder is not zero and quotient remain same then it is repeating.

$-\frac{2}{3}=-0.666.....$

$-\frac{3}{5}=-0.6$

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

$\frac{11}{20}=0.55$

Therefore, The repeating decimal number is $-\frac{2}{3}=-0.666.....$
