What five numbers round to 10000 when rounded to the nearest hundred?

Answer 1

10000

Answer 2

When rounding to the nearest hundred, half of the numbers will be above it and half will be below it.

half of 100 is 50. Thus:

• all numbers greater than or equal to 10000 - 50 = 9950 will round up to 10000; and
• all number less than 10050 will round down to 10000.

Considering only whole numbers, there are 100 numbers that round to 10000 to the nearest hundred:

9950, 9951, 9952, 9953, 9954, 9955, 9956, 9957, 9958, 9959, 9960, 9961, 9962, 9963, 9964, 9965, 9966, 9967, 9968, 9969, 9970, 9971, 9972, 9973, 9974, 9975, 9976, 9977, 9978, 9979, 9980, 9981, 9982, 9983, 9984, 9985, 9986, 9987, 9988, 9989, 9990, 9991, 9992, 9993, 9994, 9995, 9996, 9997, 9998, 9999, 10000, 10001, 10002, 10003, 10004, 10005, 10006, 10007, 10008, 10009, 10010, 10011, 10012, 10013, 10014, 10015, 10016, 10017, 10018, 10019, 10020, 10021, 10022, 10023, 10024, 10025, 10026, 10027, 10028, 10029, 10030, 10031, 10032, 10033, 10034, 10035, 10036, 10037, 10038, 10039, 10040, 10041, 10042, 10043, 10044, 10045, 10046, 10047, 10048, 10049
