Question 2:

Observe the number line and answer the questions.

(1) Which number is indicated by point B?

(2) Which point indicates the number 134?

(3) State whether the statement, 'the point D denotes the number 52, is true of false.

ANSWER:

(1) We observe that each unit on the number line is divided into 4 equal parts.

Now, B is the tenth point on the left of 0.

So, B indicates −104 on the number line .

(2) 134=74=7×14

So, the seventh point on the right of 0 is C that indicates 134 on the number line.

(3) The point D is the tenth point on the right of 0. So, D indicates 104 on the number line.

Now, 104 = 52

So, D denotes 52 on the number line. Hence, the given statement is true.
