(5 x 5) - 5 - (5/5) = 19
285 15 x 19 (3 x 5) x 19 The factor tree has reduced 285 to its prime factors: 3, 5, and 19.
5 x 19 = 95.
95
5 x 19 is 95
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
% rate:= (5/19) x 100%= 0.2632 x 100%= 26.32%
Multiply 19 by any five counting numbers. 19 x 1 = 19 19 x 2 = 38 19 x 3 = 57 19 x 4 = 76 19 x 5 = 95
