Question

Arrange the following numbers in descending order. $-2,\frac{4}{-5},\frac{-11}{20},\frac{3}{4}$

• A. $\frac{3}{4}>-2>\frac{-11}{20}>\frac{4}{-5}$
• B. $\frac{3}{4}>\frac{-11}{20}>\frac{-4}{5}>-2$
• C. $\frac{3}{4}>\frac{4}{-5}>-2>\frac{-11}{20}$
• D. $\frac{3}{4}>\frac{4}{-5}>\frac{-11}{20}>-2$

Answer 1

The correct option is B $\frac{3}{4}>\frac{-11}{20}>\frac{-4}{5}>-2$

By verification process, $A\to \frac{3}{4},\frac{-2}{1},\frac{-11}{20},\frac{-4}{5}$

$3\times 1,-2\times 4$

3, - 8

Correct, $-2\times 20,-11\times 1$

- 40, - 11

Wrong.

$B\to \frac{3}{4},\frac{-11}{20},\frac{-4}{5},\frac{-2}{1}$

$3\times 20,-11\times 4$

60, - 44

$\frac{3}{4}>\frac{-11}{20}$ $-11\times 5,-4\times 20$

- 55, - 80

$\because \frac{-11}{20}>\frac{-4}{5}$

$-4\times 1,-2\times 5$

- 4, - 10

$\because \frac{-4}{5}>-2$
