Kareem took 4 2/5 hours to clean the bathroom. Then he took 2 1/4 hours to clean the den. How much total time did Kareem take to clean the two rooms?

Write your answer as a mixed number in simplest form.

  6 13/20 hours

Step-by-step explanation:

Addition of fractions requires they be expressed using a common denominator. Here, that will be 5·4 = 20, and the two fractions can be written as ...

  2/5 = 8/20

  1/4 = 5/20

Then the sum of the mixed numbers is ...

  (4 2/5) +(2 1/4) = (4 +2) +(2/5 +1/4) = 6 +(8/20 +5/20)

  = 6 13/20

It took Kareem 6 13/20 hours to clean the two rooms.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
