This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
$\frac{3}{8}, \frac{2}{5}, \frac{9}{11}, \frac{5}{6}, \frac{6}{7}$

Fractions Ascending Order Comparison

To find the fractions in ascending order, we need to arrange them from the smallest value to the largest value. We can compare fractions by converting them to decimals or finding a common denominator. Converting to decimals is often simpler for comparison.

Decimal Conversion of Fractions

Let's convert each fraction provided in the options to its decimal form:

FractionDecimal Value
$\frac{3}{8}$
0.375
$\frac{2}{5}$
0.4
$\frac{9}{11}$
~0.81818...
$\frac{5}{6}$
~0.83333...
$\frac{6}{7}$
~0.85714...

Identifying Ascending Order

Now, we check the order of these decimal values for each option:

  • Option 1: $\frac{3}{8}, \frac{2}{5}, \frac{9}{11}, \frac{5}{6}, \frac{6}{7}$ Decimal values: $0.375, 0.4, \approx 0.818, \approx 0.833, \approx 0.857$. This sequence is $0.375 < 0.4 < 0.818 < 0.833 < 0.857$. This matches ascending order.
  • Option 2: $\frac{2}{5}, \frac{6}{7}, \frac{9}{11}, \frac{3}{8}, \frac{5}{6}$ Decimal values: $0.4, \approx 0.857, \approx 0.818, 0.375, \approx 0.833$. This is not in ascending order ($0.857 > 0.818$ and $0.375 < 0.833$).
  • Option 3: $\frac{9}{11}, \frac{6}{7}, \frac{5}{6}, \frac{2}{5}, \frac{3}{8}$ Decimal values: $\approx 0.818, \approx 0.857, \approx 0.833, 0.4, 0.375$. This is not in ascending order (it's closer to descending).
  • Option 4: $\frac{6}{7}, \frac{5}{6}, \frac{9}{11}, \frac{2}{5}, \frac{3}{8}$ Decimal values: $\approx 0.857, \approx 0.833, \approx 0.818, 0.4, 0.375$. This is in descending order.

The correct sequence in ascending order is $\frac{3}{8}, \frac{2}{5}, \frac{9}{11}, \frac{5}{6}, \frac{6}{7}$.
