How can you compare ratios to solve problem

To compare ratios let's look at an example  which would be easier to explain.3: 4 = 6: xnow, ratios are basically fractions. so we can write it like this: 3/4 = 6/x3x=24 (cross multiply)x=8 (divide each side by 3)another way to too look at this way: 3: 2 and 9: 5, which ratio is bigger.3/2 and 9/59/5 is bigger.so 9: 5 is bigger.hope this
