No, three fifths is bigger than four ninths.

There are many ways you can answer this question.

You could do it visually by drawing two circles. Divide one into 9 pieces and one into 5 pieces. Colour in 4/9 and 3/5 and see which one looks bigger. However this method is time consuming, not to mention not extremely accurate.

The best way to do it would be mathematically. In order to compare fraction you need to have a common denominator. Trying to compare fractions without a common denominator is like trying to compare apples and Oranges.

In order to find a common denominator find a number that both 9 and 5 are factors of (being a factor of something means that when you divide that number by its factor the result will be a whole number). It doesn't have to be the lowest number, just any number will do. The easiest way to do this is to just multiply the two numbers together. That way you are 100% sure both 9 and 5 will be factors.

9*5 = 45

So now we must convert both fractions to be out of 45

4/9 = x/45

(4/9)*45 = x

x = 20

3/5 = y/45

(3/5)*45 = y

y = 27

Therefore

4/9 = 20/45

3/5 = 27/45

Which one is bigger? 27>20 Therefore 3/5 is bigger than 4/9
