are you serious. what grade are you in, birth? four-fifths is greater than three-tenths.
Two fifths is greater than three tenths, because the smaller the denominator (top number), the bigger the piece (bottom number).
3/10 is greater.
2/5 is greater.
three fifths is greater. if the number on top is the same, then the one with the least on bottom is the greatest.
The answer is actually 3 fifths. This is because if you double the bottom to equal 10 you have to double the top leaving it 6 tenths which is grater than four tenths.
