Question

1/3+1/4 1/5+1/2 1/3+1/6 1/8+1/4 4/5+1/20 7/10+3/100 7/6+5/12 9/10+2/5
Efectuati adunarile,simplificati(eventual)rezultatul obtinut pana la o fractie ireductibila

Answer 1

1/3 +1/4= 4/12+3/12=7/12
1/5 + 1/2= 2/10+5/10=7/10
1/3 + 1/6 = 2/6+1/6=3/6=1/2
1/8+1/4=1/8 +2/8=3/8
4/5+1/20=16/20+1/20=17/20
7/10+3/100=70/100+3/100=73/100
7/6+5/12=14/12+5/12=19/12
9/10+2/5=9/10+4/10=13/10
Succes :))

Answer 2

1/3+1/4(amplifici cu 4 , in primul caz, si cu 3 in al doilea= 4/12+3/12=7/12

1/5+1/2 (amplifici cu 2 in primul caz si cu 5 in al doilea) =2/10+5/10=7/10

1/3+1/6(amplifici cu 2 prima fractie) =6/18+ 3/18= 9/18 (simplifici cu 3) = 3/6 (simplifici iar cu 3) =1/2

1/8+1/4(amplifici cu 2 doar la a doua) = 1/8+2/8=3/8

4/5+1/20(amplifici cu 4 prima fractie) = 16/20+1/20=17/20

7/10+3/100 (amplifici cu 10 prima fractie) =70/100+3/100= 73/100

7/6+5/12 (amplifici prima fractie cu 2) = 14/12+5/12=19/12

9/10+2/5 (amplifici a doau fractie cu 2) = 9/10 + 4/10= 13/10
