63 + (12 x 15) = 63 + 180 = 243
not by a whole number 15 x 4 = 60 15 x 5 = 75 63/15 = 21/5 = 42/10 = 4.2
x + 3(x+1) = 63; x + 3x + 3 = 63; 4x = 60; x = 15. 15 + 3 x 16 = 15 + 48 = 63. The Numbers are 15 & 16.
Yes!!! 15 times , leaving a remainder of '3' 4 x 15 = 60 60 + 3 = 63

1 x 315, 3 x 105, 5 x 63, 7 x 45, 9 x 35, 15 x 21, 21 x 15, 35 x 9, 45 x 7, 63 x 5, 105 x 3, 315 x 1
63 x 63 = 3969
The first ten positive integer multiples of 63 are as follows: 1 x 63 = 63 2 x 63 = 126 3 x 63 = 189 4 x 63 = 252 5 x 63 = 315 6 x 63 = 378 7 x 63 = 441 8 x 63 = 504 9 x 63 = 567 10 x 63 = 630
63 is 420% of 15. (63/15 * 100 = 420)
The positive integer factors of 315 are 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, and 315 315 = 1 x 315, 3 x 105, 5 x 63, 7 x 45, 9 x 35, 15 x 21
Sticking to integers: 7 x 9 = 63 3 x 21 = 63 1 x 63 = 63
o resultado eh x=7 resolução; X x 9 = 63 X = 63/9 X = 7
