15. Mr. Clements painted his barn for hours in the morning. He painted  his barn hours in the morning. He painted the barn for hours in the afternoon.Select True or False for each statement.

15a. A common denominator of the mixed numbers is 20.

15b. The amount of time spent painting in the morning can be rewritten as

15c. Mr. Clements spent

hours longer painting in the afternoon than the morning.

16. Tom exercised:

hour on Monday and

hour on Tuesday. Part A. Complete the calculations below to write equivalent fractions with a common denominator.

15a)  True

Turning the Mixed Numbers into Improper ones:

He painted the his barn:

Keep the denominator, and for the numerator multiply the denominator 5 by 3 and add 3 = 18. (In the morning).

(In the afternoon)

The Prime factorization help us to obtain the common denomination, i.e. 20

15b) False

This is a matter of simplification. In this mixed number, the fraction can be simplified this way:

15c) True

Subtracting the working hours, knowing the common denominator by prime factorization is 20.

For Mixed Numbers:

For the same mixed numbers turned into improper fractions:

Notice that:

16A

Equivalent fractions are fractions multiplied by a same constant, on the numerator and denominator:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
