Amy studies two plant cells in biology class One cell measures 8 x 10 meter across. The other cell measures 4 x 10 meter across
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 by 10-to get 10 Then she would have concluded that the larger cell is 2 x 10-7 _ 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-to get 10- she should have then multiplied 0.5 by 10-to
conclude that the larger cellis 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 x 10 to find that the larger cell is 5 times the size of the smaller cell,
