Question

i) 3+ 1/2
j) 4/3+0
k) 1/7 + (- 4/3) + 6/7 + 1/3
l) 100/200+101/303+ 50/300
m) 3 3/4 + ( -3 1/4)

Answer 1

1)3+1/2=7/2
2)4/3
3)1/7-4/3+6/7+1/3=7/7-3/3=1-1=0
4)100/200+101/303+50/300=1/2+1/3+1/6
=pe prima o amplificam cu 3,a doua cu 2
3+2+1/6toate pe aceeași fracție
=6/6=1
5)3 3/4+(-3 3/4)=
15/4-13/4=2/4=1/2
