Пошаговое объяснение:
1) ( 9 3/7+ 2 9/16)- 5 3/7=(9 3/7-5 3/7)+ 2 9/16=4 + 2 9/16=6 9/16
2) ( 4 5/8+1 6/11) - 6/11= 4 5/8+ ( 1 6/11-6/11)=4 5/8+ 1=5 5/8
3) 10 5/14-(3 5/14+2 9/34)=10 5/14-3 5/14- 2 9/34=7 - 2 9/34=6 34/34-2 9/34=4 25/34
4) 7 1/7-( 2 6/13+ 3 1/7)=7 1/7-3 1/7- 2 6/13=4- 2 6/13=3 13/13-2 6/13=1 7/13
