Six tenths but then you have to simplify it so then it would be three fifths
Nine tenths plus two fifths minus one fourth is equal to 1.05
4 and two fifths
six and three fifths
Six tenths but in the simplest form it is three fifths! Simplest form is just simplifying to make things more easier on yourself!
3.4 - 1.9 = 1.5 = 1 and 1/2
