Which of the following decimals are arranged in ascending order?

  1. $0.5, 0.42, 0.382$
  2. $11.001, 11.1, 11.21$

  4. $8.9, 8.86, 8.094$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Ascending order means increasing the order of a series, sequence or pattern.

Option A= $0.5>0.42>0.382$ : Numbers are in descending order
Option B= $11.001<11.1<11.21$ : Numbers are in ascending order
Option C= $20.3<30.02>23.25$ : Numbers are not in proper order
Option D= $8.9>8.86>8.094$ :Numbers are in descending order.

Option $B$ is the correct answer.

Which of the following fractions are in order from the least to the greatest?

  1. $\dfrac {1}{2}, \dfrac {2}{3}, \dfrac {2}{6}$
  2. $\dfrac {1}{2}, \dfrac {2}{6}, \dfrac {2}{3}$
  3. $\dfrac {2}{6}, \dfrac {2}{3}, \dfrac {1}{2}$
  4. $\dfrac {2}{6}, \dfrac {1}{2}, \dfrac {2}{3}$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

First convert the given fractions into like fractions.
L.C.M. of $2, 3, 6 = 6$
So,
$\dfrac {1}{2} = \dfrac {1\times 3}{2\times 3} = \dfrac {3}{6}; \dfrac {2}{3} = \dfrac {2\times 2}{3\times 2} = \dfrac {4}{6}; \dfrac {2}{6} = \dfrac {2\times 1}{6\times 1} = \dfrac {2}{6}$
So, ascending order is,
$\dfrac {2}{6}, \dfrac {3}{6}, \dfrac {4}{6}$ i.e. $\dfrac {2}{6}, \dfrac {1}{2}, \dfrac {2}{3}$.

Smallest $6$-digit number that can be formed using $9,2,6,0,3,1$ (using each digit only once) is _________ .

  1. $012369$
  2. $102369$
  3. $106239$
  4. $103269$

B Correct answer
Explanation

To find the smallest digit start arranging the numbers in ascending order.

However, $0$ cannot be the first or else the number would become $5$ digit.
Therefore, $102369$ is the correct answer.
