Answer 1

A)13-1  3/10 * 5/3=13-13/10*5/3=13-13/6=13-2 1/6=10 5/6                                                  b)21-(12 125/1000-1 5/6=21-(12 1/8 - 1 5/6)=21-(12 3/24 -1 20/24)=21-11 27/24 - 1 20/24)=21-10 7/24 =20 24/24-10 7/24=10 17/24                                                                 c)(5 3/4+4/100)*10/3=(5 75/100+4/100)*10/3=5 79/100*10/3=579/100*10/3=193/10=19 3/10                                                                                                                                   d)=25/8+1,75=25/8+1 3/4=3 1/8 +1 6/8 = 4 7/8                                                             e)=1 3/4 : (4 1/2*11/6)=7/4 : (9/2*11/6)=7/4 : 33/4=7/4*4/33=7/33
