Question

Which of the following are in descending order of their value?

Options:

A . $MF#%\dfrac{7}{8}, \dfrac{4}{7}, \dfrac{3}{7}, \dfrac{2}{5}, \dfrac{1}{4}, \dfrac{1}{6}$MF#%

B . None of these

C . $MF#%\dfrac{1}{4}, \dfrac{2}{5}, \dfrac{4}{7}, \dfrac{1}{6}, \dfrac{3}{7}, \dfrac{7}{8}$MF#%

D . $MF#%\dfrac{1}{4}, \dfrac{2}{5}, \dfrac{4}{7}, \dfrac{5}{6}, \dfrac{6}{7}, \dfrac{7}{8}$MF#%

Answer: Option A

Answer : Option A

Explanation :

1/4= 0.25 and 2/5 = 0.4
Hence,2/5 > 1/4

Hence, $MF#%\dfrac{1}{4}, \dfrac{2}{5}, \dfrac{4}{7}, \dfrac{5}{6}, \dfrac{6}{7}, \dfrac{7}{8}$MF#% is not in descending order
Similarly, $MF#%\dfrac{1}{4}, \dfrac{2}{5}, \dfrac{4}{7}, \dfrac{1}{6}, \dfrac{3}{7}, \dfrac{7}{8}$MF#% is also not in descending order

7/8 = 0.8 (Taken only one digit after the decimal point) 4/7 = 0.5 (Taken only one digit after the decimal point) 3/7 = 0.42 (Taken only two digits after the decimal point) 2/5 = 0.4 1/4 = 0.2 (Taken only one digit after the decimal point) 1/6 = 0.1 (Taken only one digit after the decimal point)

$MF#%\text{Hence, }\dfrac{7}{8}, \dfrac{4}{7}, \dfrac{3}{7}, \dfrac{2}{5}, \dfrac{1}{4}, \dfrac{1}{6}\text{ is in descending order}$MF#%
