The third one tells us the price is $12 per liter, that is to say, the top number is twelve times the bottom number.
.25 × 12 = $3
.7 × 12 = $8.40
2.5 × 12 = $30
3.52 × 12 = $42.24
$57.60 / 12 = 4.80 liters
To round a number, you look to the next place to the right of what you want to round to... for example, if you want to round to the nearest hundredth, you look to the thousandths place to see whether the hundredths place rounds up or down.
0.04 is already at the hundredths place so the thousandths place is zero... the answer to the nearest hundredth is 0.04.
For 0.2%, you have to convert the percentage to a decimal by dividing by 100 (move the decimal 2 places to the left).
0.2% = 0.002
So now to round to the nearest hundredth, we look to the thousandths place. The thousandths place has a 2 in it so the hundredths place rounds down. 0.2% total he nearest hundredth is 0.
