Question 1: Put these numbers in ascending order:

0.1, 0.01, 1, 11, 101, 10.1, 0.11

Question 2: Put these numbers in descending orders:

10, -1, 30, -8, -12, 0.1, -0.1

Q1 Solution: ‘Ascending’ means we want to start with the smallest value and end with the largest. To do this, you should cross the smallest number out once you find it and write it down, and then repeat for the next smallest number and so on, until you’ve crossed out all values.

For this question, we can see that there are 3 numbers smaller than 1, and of those, 0.01 is the smallest. So, we start by crossing off 0.01 in our initial list and then writing it down. The next smallest of the 3 is 0.1, so we cross that off and write it down next to the first number we wrote. Continuing this, we get the list of numbers in ascending order to be

0.01,0.1,0.11,1,10.1,11,101

Q2 Solution: ‘Descending’ means we want to start with the biggest value and end with the smallest. To do this, you should cross the biggest number out once you find it and write it down, and then repeat for the next biggest number and so on, until you’ve crossed out all values.

For this question, firstly recall that with negative numbers, the higher the number after the minus sign is, the smaller the number. For example, -5 is smaller than -2.

So, we can see that there are 3 positive numbers, and of those, 30 is the biggest. So, we start by crossing off 30 in our initial list and then writing it down. The next biggest of the 3 is 10, so we cross that off and write it down next to the first number we wrote. Continuing this, we get the list of numbers in descending order to be

30,10,0.1,-0.1,-1,-8,-12
