Exercise 1 Page 106

We are asked to calculate 8 % of 50. Let's do this by writing the percent as a fraction and then multiplying it by 50. Recall that we can write the percent as a fraction by writing the number part as a numerator over 100. 8 % = 8/100 Notice that we can also reduce the fraction that we got.
