Answer 2

1.5 litres was left in the container.

The third and fourth pieces when put together is 5.366 metres longer.

• The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-). The operation of subtraction is used to calculate the difference between two numbers. If you have an object group and remove a couple of them, the object group gets smaller.
• One-digit numbers can be subtracted in a straightforward manner when addressing subtraction issues, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on. While resolving these issues, we can run across situations where borrowing is necessary in some cases and not in others. Another name for subtraction with borrowing is regrouping.

• Here, according to the given information, we are given that,

Dana filled the container with 3.5 liters of water.

Now, subtracting the amount of water her mother took, we get,

$3.5 - (0.75 + 1.25) =$ $1.5$ litres.

Hence, 1.5 litres was left in the container.

• Here, according to the given information, we are given that,

The first piece was 0.75 meter and the second was 2.278 meters

Then, adding we get, $0.75 + 2.278 = 3.028$ metres.

Again, the third was 6.11 meters, and the fourth was 2.278 meters.

Then, adding, we get, $6.11+2.278 = 8.388$ metres.

Hence, difference between the third and fourth pieces when put together and the first and second pieces combined = $8.388 - 3.028 = 5.36$ metres.

Hence, the third and fourth pieces when put together is 5.366 metres longer.
