Is four sevenths the same as two fifths?

Answer 1

To compare two fractions, find a common denominator (multiplying the two denominators will always give you a common denominator), convert both fractions to the common denominator, then compare.

Another - actually easier - way to compare two fractions is to convert both to decimal. Just pick up a calculator, and divide the numerator by the denominator.

Answer 2

4/7 does not equal 2/5. If we find a common denominator to compare them, we have 4/7 = 20/35, and 2/5 = 14/35, so 4/7 is greater than 2/5.
