Answer: Finding the equivalent decimals of the amounts sold, we have that the amounts sold were the same in: Weeks 2 and 3.How to find the equivalent decimals?For a fraction, we have to divide the numerator by the denominator to find the equivalent decimal.For a percentage, we just have to divide the percentage by 100%.Hence, for the three weeks, the equivalent amounts are given by:Week 1: 4/9 = 0.4444.Week 2: 40% = 40/100 = 0.4.Week 3: 18/45 = 0.4.Hence the amounts in Weeks 2 and 3 are the same.
