Answer: If two fractions already have the same demoninator (bottom parts), as in this case, that IS the common denominator. You need no more calculations for this part (the part of finding the common denominator).
20
two fifths
Multiply two fifths by two to get a common denominator. Then you will have 4 tenths plus three tenths. then add straight across and you will get seven tenths.
No three fifths is not equal to two sixths
six and three fifths
20
Two and two fifths. Five minus two and three fifths = two and two fifths
