In order to find the number of withdrawals that Elisa and Ana drew from their bank accounts, just divide the total amount of money that was withdrawn by the amount that was withdrawn each time they visited the bank.
Elisa: $140 ÷ $20 = 7 withdrawals
Ana: $270 ÷ $45 = 6 withdrawals
As you can see, Elisa withdrew one more time than Ana did. Elisa will be your answer. You can justify this answer with the division we did to get this answer.
Elisa made a greater number because when you divide $140 by $20 you get 7. So that is seven Twenty dollar bills. For Ana, you divide $270 by $45 and you get 6. So for Ana you get 6 withdrawals of $45.
1.004 * 10^5 all scientific notation equations have to be a number greater than 1 but less than 10 then multiplied by 10 to the power of (move the decimal point to the right however many times you need, in this case 5) :)
