Answer 7

First, you're coming to want to find the least common denominator of both 18 and 21. This would be 3. Now you can simplify 18/21 by dividing both numbers by 3 (the least common denominator). The new simplified equation would be 6/7. Now, using this, it'll be easier to compare your ratios to the given possible answers. You might notice going through them that 6 times 5 equals 30 and 7 times 5 equals 35. This means that the ratio of 6/7 (18/21) equals 30/35. It's very similar to solving fractions. Hope this helps!
