Draw a number line and answer the following: |
(a) Which number will we reach if we move 4 numbers to the right of - 2? |
(b) Which number will we reach if we move 5 numbers to the left to 1? |
(c) If we are at - 8 on the number line, in which direction should we move for each - 13? |
(d) If we are at - 6 on the number line, in which direction should we move for reach - 1? |
Answer:
(a) We start from - 2 and proceed 4 units to the right of - 2 to reach 2 as shown in the figure. Hence, we will reach the number 2. (b) We start from 1 and proceed 5 units to left of 1 to reach - 4 as shown in the figure. Hence, we will reach the number - 4. (c) If we are at - 8 on the number line and we want to reach - 13 then we should move to the left of - 8, \[\therefore \]\[13<8\]. (d) If we are at - 6 on the number line and we want to reach - 1 then we should move to the right of - 6. \[\therefore \] \[1>6\]
