71 13/60+3/8:(13-12 21/22)+9/10-71 11/30+6•4 11/24

Question

71 13/60+3/8:(13-12 21/22)+9/10-71 11/30+6•4 11/24

Answer 1

13-12 21/22=12 22/22-12 21/22=1/22
3/8:1/22=3/8*22/1=33/4=8 1/4
6*4 11/24=6*107/24=107/4=26 3/4
71 13/60+8 1/4+9/10-71 11/30+26 1/4=(71 13/60-71 22/60)+(8 1/4+26 1/4)+
9/10=-9/60+34 2/4+9/10=-3/20+34 10/20+18/20=34 25/20=35 5/20=35 1/4
