Question

Ayuda matemática soy de primaria

Answer 1

Explicación paso a paso:

2/9 + 2/9 = 2+2/9 = 4/9

2/9 + 1/9 = 2+1/9 = 3/9

2/9 + 4/9 = 2+4/9 = 6/9 (simplificar)= 2/3

2/9 + 3/9 = 2+3/9 = 5/9

3/9 + 2/9 = 3+2/9 = 5/9

3/9 + 1/9 = 3+1/9 = 4/9

3/9 + 4/9 = 3+4/9 = 7/9

3/9 + 3/9 = 3+3/9 = 6/9 (simplificar)= 2/3

1/9 + 2/9 = 1+2/9 = 3/9 (simplificar)= 1/3

1/9 + 1/9 = 1+1/9 = 2/9

1/9 + 4/9 = 1+4/9 = 5/9

1/9 + 3/9 = 1+3/9 = 4/9

4/9 + 2/9 = 4+2/9 = 6/9 (simplificar)= 2/3

4/9 + 1/9 = 4+1/9 = 5/9

4/9 + 4/9 = 4+4/9 = 8/9

4/9 + 3/9 = 4+3/9 = 7/9
