Answer 1

Answer 2

(6/33 + 10/22 - 1/20 ) + ( 2intreg 3/4 + 1/45)=
2intreg 3/4= (2x4+3)/4= 11/4
(6/33 + 10 /22 - 1/20 ) + ( 11/4 + 1/45)=
in prima paranteza aducem la acelasi numitor , numitorul comun este 660
in a doua paranteza numitorul comun este 180
(( 6x20 )/660 + (10x30)/660 - 33/660) + ((11x45)/180 + 4/180)=
( 120 /660 + 300/660 -33/660 ) + ( 495 /180+ 4/180)=
387/ 660 + 499/180= 
387 /660 = simplific cu 3= 129/220
129 /220 + 499/180=
aducem la acelasi numitor , numitorul comun este : 1980
(129 x 9)/1980 + (499x11)/1980=
1161/1980 + 5489/1980= 6650/1980 simplific cu 10 = 665/198
