Answer: 1.5% of 50 is:
P = percentage = 1.5%
B = base = 50
R = rate = P/100 = 0.015
n = B * R = 50 * 0.015 = 0.75
Therefore, 1.5% of 50 is 0.75.
2.2% of 8 is:
P = percentage = 2.2%
B = base = 8
R = rate = P/100 = 0.022
n = B * R = 8 * 0.022 = 0.176
Therefore, 2.2% of 8 is 0.176.
3.12% of 150 is:
P = percentage = 3.12%
B = base = 150
R = rate = P/100 = 0.0312
n = B * R = 150 * 0.0312 = 4.68
Therefore, 3.12% of 150 is 4.68.
