Question

Use a number line to write the following integers in descending (decreasing) order :

(i) -10, 0, 3, -4, 12, 11, -1 and 5

(ii) -4, 3, -8, -12, -7 and 6.

Answer 1

(i) -10, 0, 3,-4, 12, 11,-1 and 5

Draw a number line for integers, as shown below, and mark on it all the given integers.

Clearly, the given integers in the descending order are :

6 > 3 > 0 > -7 > -8 > -10 > – 12

(ii) -4, 3, -8, -12, -7 and 6.

Draw a number line for integers, as shown below, and mark on it all the given integers.

Clearly, the given integers in the descending order are :

6 > 3 > -4 > -7 > -8 > -12
