Question

During a clinical study, a medical company found that 3 out of 70 people experienced a side effect when using a certain medicine. The company predicts 63,000 people will use the medicine next year. How many people are expected to experience a side effect?​

Answer 1

2,700 people are expected to experience a side effect.
3 divided by 70 = 0.042857142857143
0.042857142857143 x 63,000 = 2,700
check work:
2,700 divided by 3 = 900
900 x 70 = 63,000
