3 - 1 3/5= 1 2/5 or 1.4
first u simplify 1 3/5 which is 8/5
the expression turns into 3 - 8/5
3 8 2
_ - _ = 1 _
1 5 5
to answer, u have to find a gcf to find the common denominators.
15/5 - 8/5 = 7/5
7/5 = 1 2/5
or
u can put them into decimal:
3 - 1.6 = 1.4
1.4 = 1 2/5
(4/10 simplified is 2/5)
so, the answer is 1 2/5 or 1.4
