You would subtract how many times Dion tagged bill with how many times bill tagged Dion, so 12 - 7 = 5
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
That's answer.
First you want to change the fractions to the same denominator
3/4 = 9/12 and 2/3 = 8/12
then you put it in ratio form...
the answer is 9:8
