Amy studies two plant cells in biology class. one cell measures 8×10−6 meter across. the other cell measures 4×10−5 meter across. question 1 part a amy compares the sizes of the cells using these steps: 1. divide the whole-number factors: 8÷4=2. 2. divide the powers of 10: 10−5÷10−6=101=10. 3. multiply the products: 2×10=20. she concludes that the larger cell is 20 times the size of the smaller cell. which correctly describes amy’s 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 10−6 by 10−5 to get 10−1. then she would have concluded that the larger cell is 2×10−1=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 10−6 by 10−5 to get 10−1. she should have then multiplied 0.5 by 10−1 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 0.5×10 to find that the larger cell is 5 times the size of the smaller cell.
