Question

2intregi5/6-(-1intreg 2/3)-(+3intregi1/4)​

Answer 1

2 5/6-(-1 2/3)-(+3 1/4)

17/6-(-5/3)-(+13/4)

17/6+5/3-13/4

5/4

Answer 2

2 intregi5/6= (2*6+5)/6=17/6

1 intreg 2/3= (1*3+2)/3=5/3

3 intregi1/4= (3*4+1)/4=13/4

17/6-(-5/3)-13/4= 17/6+5/3-13/4 amplificam pe prima fractie cu 2, a doua cu 4 si a treia cu 3

34/12+20/12-39/12=54/12-39/12=15/12 simplificat cu 3 = 5/4
