If Marci deposited 7/8 of $320.00 in her checking account, then she deposited ____ dollars.
Marci deposited $280.00 in her checking account.
To find out how much Marci deposited, we calculate 7/8 of $320.00, which equals $280.00. This calculation shows that the amount she deposited represents a significant portion of her total account balance.
This choice represents only 3/8 of $320.00, which is not the correct fraction of the total amount Marci deposited. Calculating 3/8 of $320 gives $120, but this does not reflect the 7/8 portion she actually deposited.
This amount corresponds to 7/16 of $320.00, which is less than the 7/8 portion. Specifically, 140 is calculated by multiplying $320 by 7/16, thus it does not represent the correct deposit amount made by Marci.
This choice is not a correct calculation for either 7/8 or a relevant fraction of $320.00. It does not relate to any specific fraction of the total amount and falls short of representing 7/8 of the total.
This option represents 3/4 of $320.00, which is equivalent to multiplying $320 by 3/4. Since Marci deposited 7/8 of her total, this amount is also incorrect and does not align with her actual deposit.
This choice correctly calculates 7/8 of $320.00. To confirm, multiplying $320 by 7/8 results in $280, which is the total amount Marci deposited into her checking account.
Marci deposited $280.00 in her checking account by calculating 7/8 of $320.00. The other choices represent incorrect fractions or amounts that do not match the calculation needed to find the total deposited. Understanding how to compute fractions of a total is essential in financial decisions and accurate account management.
