*I think you should divide 750 by 5 (150) and subtract 4, because you are not going to include the 5 10, 15, and 20, which are multiples of 5 and not included in your parameters of 25 - 750There are 20 multiples of 5 in every 100, so 20 x 7 = 140 multiples between 0 and 750. There would be 1/2 (20) because 50 is half of 100, and you need to add another 10 multiples. That gives you 150 multiples multiples of 5 between 0 and 750. Now, subtract the 4, and you get 150-4 = 146*

*I'd write the equation like this: [(20 x 7) + (10 x 1)] - 4 = [140 + 10] - 4 = 150 - 4 = 146*

*or, using Chellanne"s formula: (750 - 25)/5 + 1= 725/5 + 1= 145 + 1 = 146*
