                  FoRMING 2-dIGIT NUMBERS

                  How many 2-digit numbers can be formed using the digits 4 and 7?

                  There are two ways to make 2-digit numbers using the given digits.
                  l  With repeating the digits:  44 and 77

                  l  Without repeating the digits: 47 and 74

                  Thus, there are four 2-digit numbers that can be made using the digits 4 and 7.

                  Example: Build the 2-digit number using the digits 6 and 9 without repetition.

                  Solution: Step 1: Start with the digit 6: 69
                               Step 2: Start with the digit 9: 96

                           Practice Time 3d

                  1.   Circle the bigger number.

                       (a)    8      51        (b)    34      68         (c)    72     49        (d)    99      55

                  2.   Circle the smaller number.

                       (a)    77     40        (b)    54      64         (c)    53     16        (d)    30      34

                  3.   Put the proper sign (>, < or =) in the              .

                       (a) 51        51        (b) 72         72         (c) 73        67        (d) 74        89

                       (e) 99        89         (f) 47        77        (g) 63         56        (h) 35        66

                  4.   Arrange the following numbers in ascending order.
                       (a)  36      57        68         49        74

                       (b)  61      43        83         32        60

                       (c)  100     70        81         65        59

                  5.   Arrange the following numbers in descending order.

                       (a) 28       40        15         35        48

                       (b)  22      49        32         26        47
                       (c)  42      49        40         13        36

                  6.  Write the 2-digit numbers formed by the following digits, given that the

                       repetition of digits is allowed.

                       (a) 3, 5                         (b)  5, 7                        (c)  4, 9
