2 1/5 - 1 3/4 + 3 5/6= Beserta caranya!

2 1/5 - 1 3/4 + 3 5/6
= 11/5 - 7/4 + 23/6
= [11(12) - 7(15) + 23(10)] / 60
= [121 - 105 + 230]/60
= 246 / 60
= 41 / 10
= 4 1/10

2x5+1/5 - 1x4+3/4 + 3x6+5/6=10+1/5 - 4+3/4 + 18+5/6=11/5-7/4+23/6=11x4-5x7/5x4+23/6=44-35/20+23/6=9/20+23/6=9x3/20x3+23x10/6x10=27/60+230/60=257/60=4 17/60=4,283
