1/9+1/27×49/100:125/8=1/9+1/27×100/49×8/125=1/9+1/27×32/245
1/9+32/6615 amplificãm pe 1/9 cu 735
735/6615+32/6615=767/6615
1/9+32/6615 amplificãm pe 1/9 cu 735
735/6615+32/6615=767/6615
1/9+1/27×49/100:125/8=
1/9+1/27×100/49×8/125=
1/9+1/27×32/245=
1/9+32/6615= aducem la același numitor 6615=
735+32/6615=767/6615
Sper că te-am ajutat!
