Step-by-step explanation:The amount of water that has evaporated is 8 1/12.

Step-by-step explanation:

Given: 17 3/4 and 9 2/3

Asked: How much water has evaporated?

Situation:

After boiling, the 17 3/4 liters of water was reduced to 9 2/3 liters.

Solution:

The first thing to do is to change mixed numbers into improper fraction. 17 3/4  will become 71/4  and 9 2/3  will become 29/3. Next, let's proceed to the solution:

71   - 29

4       3

= 213 - 116      Find the LCD which is 12.

 12     12

= 97

12

= 8 1/12

Therefore, the amount of water that has evaporated is 8 1/12. Code 7.3.1.7.
