5/4 9/10 describe two methods you could use to compare the fractions

You could cross multiply I believe and see if they are equivalent. There is another way to do it. I’m not sure. I guess you could plug the numerator into a calculator and then divide by the denominator by both. You could then get decimals and see which is bigger.

You can keep,flip,change a.k.a KFC and find your answer or cross multiply the two fractions

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
