Answers (1)

(a) 728 \times 101= 728 \times (100 + 1)

                     = 728 \times 100 + 728 \times 1

                     = 72800 + 728

                     = 73528

(b) 5437 \times 1001 = 5437 \times (1000 + 1)

                          = 5437 \times 1000 + 5437 \times 1

                          = 5437000 + 5437

                          = 5442437

(c) 824 \times 25 (800 + 24) \times 25 = (800 + 25 - 1) 25

                                             =800 \times 25+25 x 25-1 \times 25

                                             = 20000 + 625 - 25

                                             = 20000 + 600

                                             = 20600

(d) 4275  \times 125 = (4000 + 200 + 100 - 25) \times 125

                         = 4000 \times 125 + 200 \times 125 + 100 \times 125 - 25 \times 125

                         = 500000 + 25000 + 12500 - 3125

                         = 534375

(e) 504 \times 35 = (500 + 4) \times 35

                    = 500 x 35 +4 \times 35

                    = 17500 + 140

                    = 17640
