Any number that ends in 5 will have 5 as a factor, so divide. 225/5 = 45 ... divide by 5 again. 45 / 5 = 9... divide by 3 9/3 = 3 The prime factorization is 3x3x5x5.

7/9 of 225 is 175.
Divide 225 by 1, 3, 5, 9 and 15. 1, 3, 5, 9, 15, 25, 45, 75, 225
5 and 1
1, 3, 5, 9, 15, 25, 45, 75, 225.
The answer depends on what you wish to do with the estimate. If you wanted to divide by 3, I would suggest 225 since 225/3 = 75. If you wanted to divide by 4 I would suggest 224 or 228 [/4 = 56 or 57]. If dividing by 5 I would suggest 225 again since 225/5 = 45.
