5/7 which means for every 7 kids, one owns a dog
You would do 21 divided by 3 and get 7.
The answer is 7 kids are in the line.

I hope this helps... if not let me know and I'll try to help again :)
Because the sofa usually sells for $800, we know that's 100% of the price.
100% = $800
Let's find 1%.
1% = $800/100
1% = $8
Next, multiply $8 by 75 to find the percent of the sofas price when it's $600.
75% = $600
We now know that $600 is 75% of the sofas original price.
100% - 75% = 25%
The percent of decrease I'm the sofas sale price is 25%.
Hope I got that right, the question was worded a little strangley so I wasn't quite sure what you were asking :)
