Amy studies two plant cells in biology class. one cell measures 8Γ10β6 meter across. the other cell measures 4Γ10β5 meter across. question 1 part a amy compares the sizes of the cells using these steps: 1. divide the whole-number factors: 8Γ·4=2. 2. divide the powers of 10: 10β5Γ·10β6=101=10. 3. multiply the products: 2Γ10=20. she concludes that the larger cell is 20 times the size of the smaller cell. which correctly describes amyβs conclusion and process? amy is correct. she divided the whole-number parts of the expressions and then the powers of 10. then she multiplied the two products to get the correct answer. amy is not correct. she should have divided 10β6 by 10β5 to get 10β1. then she would have concluded that the larger cell is 2Γ10β1=0.2 times the size of the smaller cell. amy is not correct. she should have divided 4 by 8 to get 0.5 and then divided 10β6 by 10β5 to get 10β1. she should have then multiplied 0.5 by 10β1 to conclude that the larger cell is 0.05 times the size of the smaller cell. amy is not correct. she should have divided 4 by 8 to get 0.5 and then multiplied 0.5Γ10 to find that the larger cell is 5 times the size of the smaller cell.
