n = number of a ball
1 - 4 / 5 = 5 / 5 - 4 / 5 = 1 / 5
number of a red balls:
n / 5 = 35 Multiply both sides by 5
n = 5 * 35 = 175
Number of a black balls :
175 * 4 / 5 = 700 / 5 = 140
140 - 35 = 105
1 - 4 / 5 = 5 / 5 - 4 / 5 = 1 / 5
number of a red balls:
n / 5 = 35 Multiply both sides by 5
n = 5 * 35 = 175
Number of a black balls :
175 * 4 / 5 = 700 / 5 = 140
140 - 35 = 105
