Question

Accepted Answer

### Convert Percent to Decimal
To convert a percentage to a decimal, divide the percentage value by 100 (or move the decimal point two places to the left).

#### 21.3%
## Step1: Divide by 100
$21.3 \div 100 = 0.213$
# Answer: 0.213

#### 5%
## Step1: Divide by 100
$5 \div 100 = 0.05$
# Answer: 0.05

#### 1.45%
## Step1: Divide by 100
$1.45 \div 100 = 0.0145$
# Answer: 0.0145

#### 117%
## Step1: Divide by 100
$117 \div 100 = 1.17$
# Answer: 1.17

#### 6.2%
## Step1: Divide by 100
$6.2 \div 100 = 0.062$
# Answer: 0.062

#### 41.87%
## Step1: Divide by 100
$41.87 \div 100 = 0.4187$
# Answer: 0.4187

### Round to the Nearest Cent
To round to the nearest cent, we look at the thousandths place (third decimal place). If it is 5 or more, we round up the hundredths place; otherwise, we leave it as is. Then we add the dollar sign.

#### 129.843
## Step1: Look at thousandths place (3)
Since $3 < 5$, we keep the hundredths place as is.
## Step2: Add dollar sign
$\$129.84$
# Answer: $\$129.84$

#### 1,203.0981
## Step1: Look at thousandths place (8)
Since $8 \geq 5$, we round up the hundredths place: $09 + 01 = 10$ (carry over the 1 to the tenths place: $0 + 1 = 1$)
## Step2: Add dollar sign
$\$1203.10$
# Answer: $\$1203.10$

#### 564.9455
## Step1: Look at thousandths place (5)
Since $5 \geq 5$, we round up the hundredths place: $4 + 1 = 5$
## Step2: Add dollar sign
$\$564.95$
# Answer: $\$564.95$

#### 2.094
## Step1: Look at thousandths place (4)
Since $4 < 5$, we keep the hundredths place as is.
## Step2: Add dollar sign
$\$2.09$
# Answer: $\$2.09$

#### 18.999
## Step1: Look at thousandths place (9)
Since $9 \geq 5$, we round up the hundredths place: $9 + 1 = 10$ (carry over the 1 to the tenths place: $9 + 1 = 10$, carry over the 1 to the ones place: $8 + 1 = 9$)
## Step2: Add dollar sign
$\$19.00$
# Answer: $\$19.00$

#### 81.111
## Step1: Look at thousandths place (1)
Since $1 < 5$, we keep the hundredths place as is.
## Step2: Add dollar sign
$\$81.11$
# Answer: $\$81.11$

### Find each amount to the nearest cent
To find a percentage of an amount, convert the percentage to a decimal and multiply by the amount, then round to the nearest cent.

#### 10% of $816$
## Step1: Convert 10% to decimal
$10\% = 0.1$
## Step2: Multiply by 816
$0.1 	imes 816 = 81.6$
## Step3: Round to nearest cent (already a decimal with one decimal place, so add a zero at the hundredths place)
$\$81.60$
# Answer: $\$81.60$

#### 125% of $7,512$
## Step1: Convert 125% to decimal
$125\% = 1.25$
## Step2: Multiply by 7512
$1.25 	imes 7512 = 9390$
## Step3: Round to nearest cent (whole number, so add .00)
$\$9390.00$
# Answer: $\$9390.00$

#### 6.2% of $1,098$
## Step1: Convert 6.2% to decimal
$6.2\% = 0.062$
## Step2: Multiply by 1098
$0.062 	imes 1098 = 68.076$
## Step3: Round to nearest cent (look at thousandths place, 6 ≥ 5, so round up hundredths place: 7 + 1 = 8)
$\$68.08$
# Answer: $\$68.08$

#### 3% of $985$
## Step1: Convert 3% to decimal
$3\% = 0.03$
## Step2: Multiply by 985
$0.03 	imes 985 = 29.55$
## Step3: Round to nearest cent (already two decimal places)
$\$29.55$
# Answer: $\$29.55$

#### 12.5% of $577$
## Step1: Convert 12.5% to decimal
$12.5\% = 0.125$
## Step2: Multiply by 577
$0.125 	imes 577 = 72.125$
## Step3: Round to nearest cent (look at thousandths place, 5 ≥ 5, so round up hundredths place: 2 + 1 = 3)
$\$72.13$
# Answer: $\$72.13$

#### 1.45% of $1,098$
## Step1: Convert 1.45% to decimal
$1.45\% = 0.0145$
## Step2: Multiply by 1098
$0.0145 	imes 1098 = 15.921$
## Step3: Round to nearest cent (look at thousandths place, 1 < 5, so keep hundredths place as is)
$\$15.92$
# Answer: $\$15.92$
