Well 1 and 6/12 add 2 and 6/12 gets a total of 4 full hours add this to the 1 and 9/12 this gets 5 and 9/12 60 min /12 is 5 min per part so 5x9 is 45 therfore he ran 5 hour 45 min
7 and 8 because the square root is 7.874
The greatest common divisor of these numbers is 12.
Answer:
. .....
Step-by-step explanation:
Let us assume the number of text books sold by <span>keller publishing = x
Then
Then </span>number of text books sold by <span>Scholastic books = 4x
The total number of text books sold = 7775
Then
x + 4x = 7775
5x = 7775
x = 1555
Then
The nu</span>mber of text books sold by Scholastic books = 4x
= 4 * 1555
= 6220
I hope the procedure is clear enough for you to understand.
