Descompune după modelul dat numerele :345.739,903,401,894,673 ,297:
732=700+30+2=7×100+3×10+2×1

Answer 1

345 = 300 + 40 + 5 = 3 x 100 + 4 x 10 + 5 x 1
739 = 700 + 30 + 9 = 7 x 100 + 3 x 10 + 9 x 1
903 = 900 + 3 = 9 x 100 + 0 x 10 + 3 x1 
401 = 400 + 1 = 4 x 100 + 1 x 1 
894 = 800 + 90 + 4 = 8 x 100 + 9 x 10 + 4 x 1 
673 = 600 + 70 + 3 = 6 x 100 + 7 x 10 + 3 x 1
297 = 200 + 90 + 7 = 2 x 100 + 9 x 10 + 7 x 1
