Answer 1

4/25+15/4=16/100+375/100=391/100=3 91/100=3,91

(1 5/6+3/5)*24=(11/6+3/5)*24=(55/30+18/30)*24=(73/30)*24=(73/5)*4=292/5=58 2/5=58,4

(1 11/16-3 7/8)*4=(27/16-31/8)*4=(27/16-62/16)*4=(-35/16)*4=-35/4=-8 3/4=-8,75

(9/16+2 3/8)*4=(9/16+19/8)*4=(9/16+38/16)*4=(47/16)*4=47/4=11 3/4=11,75

1 1/12 /(1 13/18-2 5/9)=13/12 /(31/18-23/9)=13/12 /(31/18-46/18)=13/12 /(-15/18)=13/12 /(-5/6)=13/12 *(-6/5)=-13/10=-1 3/10=-1,3
