Question

Dintr-un cablu de 28 3/4 m se taie mai intai 7 1/2 m,apoi 3 1/3 m. Cati metri de cablu mai raman?

Answer 1

28 3/4 - 7 1/2 - 3 1/3 = 28 9/12 - 7 6/12 - 3 4/12 = 21 3/12 - 3 4/12 = 18 11/12 metri

Answer 2

283/4-71/2-31/3=849/12-426/12-124/12=299/12
daca acolo sunt intregi
28 3/4 - 7 1/2 - 3 1/3 = 115/4-15/2-10/3=345/12-90/12-40/12=215/12
