= 1.6
Calculation steps
Divide: -8 : (-3) = 2.66666666667 = 8
3
Add: 2
5
+ 8
3
= 2 · 3
5 · 3
+ 8 · 5
3 · 5
= 6
15
+ 40
15
= 6 + 40
15
= 46
15
The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 3) = 15
Divide: 4 : (-5) = -0.8 = -4
5
Add: 46
15
+ (-4
5
) = 46
15
+ (-4) · 3
5 · 3
= 46
15
+ (-12
15
) = 46 + (-12)
15
= 34
