Answer 2

Calculation of Hours Spent on Each Day

To calculate the number of hours spent by the grandmother on each day, we need to divide the total number of hours she worked by the number of jars she prepared each day.

On the first day, the grandmother prepared 12 identical jars of compote in 5 hours. Therefore, the number of hours spent on each jar can be calculated as:

Hours spent on each jar on the first day = Total hours spent / Number of jars prepared

Hours spent on each jar on the first day = 5 hours / 12 jars

To find the hours spent on each jar on the second day, we can use the same formula:

Hours spent on each jar on the second day = Total hours spent / Number of jars prepared

Hours spent on each jar on the second day = 5 hours / 18 jars

Let's calculate the values:

Hours spent on each jar on the first day = 5 hours / 12 jars = 0.4167 hours per jar

Hours spent on each jar on the second day = 5 hours / 18 jars = 0.2778 hours per jar

Therefore, the grandmother spent approximately 0.4167 hours on each jar of compote on the first day and approximately 0.2778 hours on each jar on the second day.
