                NumberS ON THe Number LINe

                In the previous classes, we have learnt how to place smaller numbers on a number
                line. Now, we shall learn how to place bigger numbers on a number line.
                example. Given below is a number line marked with numbers from 1,000 to 1,100 at
                intervals of 10.

                                 1,011                           1,047

                      1,000    1,010    1,020   1,030    1,040    1,050   1,060    1,070    1,080   1,090    1,100

                Here, 1,011 and 1,047 are marked. Can you mark 1,023, 1,069 and 1,085?

                Solution. Yes, we can mark the numbers 1,023, 1,069 and 1,085 as shown below.
                                 1,011     1,023                 1,047            1,069         1,085

                      1,000    1,010    1,020   1,030    1,040    1,050   1,060    1,070    1,080   1,090    1,100

                            Exercise 1B

                    1.   Which  numbers  lie between 20,525 and  20,575 among  the following  numbers?
                        Circle them.

                            20,555    20,450    21,050    20,529    20,584    20,604

                    2.  Do as directed.

                        a.  Mark the following numbers on the number line given below.

                            52,300     55,500     51,400     56,200     58,100     54,900

                                  51,000   52,000   53,000   54,000   5,5000   56,000    57,000   58,000   59,000

                        b.  Fill in the blanks and mark the following numbers on the number line given below.
                                              87,500     90,250     86,750    92,500

                             85,000         87,000                                                             96,000

                    3.  Count and write the next five numbers in each case. One has been done for you.

                        a.  Count by tens.

                               i.  24,364     24,374,  24,384,  24,394,  24,404,  24,414
