Question

Suma a doua nr este 36,25, iar diferenta lor este 24intregi 5/6. Sa se afle nr

Answer 1

a+b=36,25

a-b=24 5/6. / le adunam

2a=36,25+149/6

2a= 217,5/6 + 149/6

2a=466,5/6

a=466,5/3

a=155,5

b=36,25-155,5

b=-119,25

Answer 2

a+b=36

a-b=24 5/6

a+b+a-b=36+24 5/6=60 5/6  (simplificam)

2a=60 5/6   a= (60 5/6) / 2=(365/6) / (2/1)= ( 365/6) * (1/2) =  365/12 = 30 si 5/12
