Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
The first and third are correct. They are equal.
The second is incorrect. This is because 1800 meters = 1.8 km (not 18 km). The answer you should have is a "less than sign" because 1.8 km is smaller than 18 km.
To go from meters to kilometers, you move the decimal point 3 spots to the left. This is the same as dividing by 1000.
To go from kilometers to meters, you move the decimal point 3 spots to the right. This is the same as multiplying by 1000.
