Final answer:
Dolores spent $13 out of $20, which as a decimal is represented by 0.65, showing she spent 65% of her total money.
Step-by-step explanation:
Dolores spent $13 of the $20 in her wallet. To find the decimal that represents the fraction of the $20 she spent, we divide the amount spent by the total amount. So, we calculate 13 ÷ 20 which equals 0.65. This means that Dolores spent 65% of her total money, or in other words, 0.65 as a decimal.
To find the fraction of the $20 that Dore spent, we need to divide the amount she spent ($13) by the total amount ($20). The fraction can be written as a decimal by dividing the numerator (amount spent) by the denominator (total amount). In this case, the decimal is 0.65.
