200
200
100 times because if you do the opposite with the numbers you have, 500/5=100
An infinite number of times. If you restrict yourself to whole numbers, 500 has 6 factor pairs.
95
1 digit number: only 1 number 2 digits number: 18 numbers 3 digits number: 76 So there are 95 numbers containing 9.
There are infinitely many such numbers.
1 - 9 = 1 10-19 = 10 20-99 = 8 So...0 - 99 = 19 100 - 199 = 100 + 19 = 119 200 - 299 = 19 300 - 399 = 19 400 - 499 = 19 500 = 0 So, in 1 - 500, the number 1 shows up this many times: 100 + (19 * 5) = 100 + 95 = 195 times
500/15 = 33.33... times.500/15 = 33.33... times.500/15 = 33.33... times.500/15 = 33.33... times.
