Joe filled a 10-cup watering can with water. He then poured some of the water on his tomato plants.
How can Joe find out how much water he used for his tomato plants?
CLEAR CHECK
Use a tape measure to find the height of the water left in the can, and then subtract the number of inches from 10.
Use a scale to weigh the water left in the can, and then subtract the number of pounds from 10.
Use a measuring cup to find the amount of water left in the can, and then subtract the number of cups from 10.
Use a measuring cup to find the amount of water used for the tomato plants.
To find out how much water Joe used for his tomato plants, he can use one of the following methods:
1. Use a tape measure to find the height of the water left in the can, and then subtract the number of inches from 10.
- Measure the height of the water in the watering can.
- Subtract this measurement from 10 to determine the amount of water used for the tomato plants.
2. Use a scale to weigh the water left in the can, and then subtract the number of pounds from 10.
- Weigh the watering can with the remaining water using a scale.
- Subtract this weight from 10 to determine the amount of water used for the tomato plants.
3. Use a measuring cup to find the amount of water left in the can, and then subtract the number of cups from 10.
- Pour the remaining water in the watering can into a measuring cup.
- Measure the amount of water in cups, and subtract this measurement from 10 to determine the amount of water used for the tomato plants.
To find out how much water Joe used for his tomato plants, he can use a measuring cup to determine the amount of water left in the watering can, and then subtract that from the total capacity of the can, which is 10 cups.
Here's how Joe can calculate it:
1. Take the watering can with the remaining water from pouring it on the tomato plants.
2. Use a measuring cup to scoop out the remaining water from the can.
3. Pour the water from the measuring cup into another container or sink.
4. Read the measurement on the measuring cup and note the amount of water left in cups.
5. Subtract this amount from the total capacity of the watering can, which is 10 cups.
For example, if the measurement on the measuring cup shows 3 cups, then Joe used 7 cups of water for his tomato plants (10 cups - 3 cups = 7 cups).
Using a measuring cup is the most precise method to determine the amount of water used for the tomato plants in this scenario.
