x + 178 = 302 Therefore, 302 - 178 = x x = 124
let the unknown no be x so, 178+x=891 transposing, x=891-178 x=713 unknown no is 713
15% = 0.15 15% off 178 = 178 - (0.15 x 178) = 151.3
4/10 x 178 = 71.2

x + 178 = 302 Therefore, 302 - 178 = x x = 124
178/200 x 100 = 89% Check---- 200 x 89% = 178
102 = 1 x 102= 2 x 51= 3 x 34= 6 x 178 factors.
let the unknown no be x so, 178+x=891 transposing, x=891-178 x=713 unknown no is 713
1 x 178, 2 x 89
178 = 2 x 89
0.70 x 178 = 124.6
