Question

Draw a bar model that shows how the number of hours in March compares with the number of hours in February of this year.

Answer 1

Okay so first we need to find how many days are in March and February. March has 31 days and because this year was a leap year February has 29 days.

The next step is to convert days to hours.
March: 31x24=744
February: 29x24=696

Now its time to graph

Answer 2

Firstly we calculate the number of hours of both months.

This year is not a Leap year. So, the number of days of February is 28

and the number of days of March is 31

So, Number of hours February has 28 × 24 = 672 hours

and, Number of hours March has 31 × 24 = 744 hours

The bar graph is the best visual representation when we have categorical data. It is drawn by using a rectangular bar where the length of the bar represents height or frequency.
