suma a doua nr este 45 aflati cele doua nr stiind ca impartind unul la celalalt ne da catul 4 si restul 5 ,metoda grafica va rog ,multumesc.

Answer 1

x:y=4 rest 5=> x=4y+5

y [..........]
x [..........][............][..........][...........][.....+5...] acolada la astea doua=45


5 segmene+5=45
5 segmente=45-5
5 segmente=40
un segment=49:5
un segment=8
daca y=1 segment=>y=8
daca x= 4 segmente+5=>x=4 ori 8+5=>x=32+5=>x=37

Answer 2

a+b=45
a:b=4 rest 5 => a=4b+5

45-5=40
40:5=8 ( b )
8×4+5=37 ( a )
