Question

o bucata de scindura care are lungimea de 4 m este taiata in doua bucati , astfel incat una sa fie cu 28 cm. mai mare decit cealalta.
citi centimetri masoara fiecare bucata?

Answer 1

4m:2= 2m=200cm
28cm:2 =14 cm
==> 200cm-14cm= 186cm
==> 200cm+14cm=214cm
1bucata: 186cm
2bucata :214 cm

Answer 2

/---------/+28cm. (a). /----------/(b). a+b=4m=400cm. b+28+b=400. 2b=400-28. 2b=372. b=372:2=186cm are b. a=186+28=214
