Answer 2
Answer:

3.) r=2: 2+4/15= 6/15=2/5

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

Answers

Answer:

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.

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
