6/3+2/2+1/4
6 1/3÷2 1/9
2 7/9÷4/9​

Answer 1

Respuesta:

3/5+2/6 = 3(6)/5(6) + 2(5)/6(5) = 28/30 = 14/15

6/3+2/2+1/4 = 6(4)/3(4) + 2(6)/2(6) + 1(3)/4(3) = 39/12 = 13/4

6 1/3÷2 1/9 = (6(3) + 1)3÷(2(9)+1)/9 = 19/3÷19/9 = 3

2 7/9÷4/9 = (2(9)+7)/9÷4/9 = 25/9÷4/9 = 25/4

Answer 2

Respuesta:

1. 1 1/15
2. 3 1/4

3. 3
4. 6 9/36

Explicación paso a paso:

1. 3/5 + 2/6= 18/30 + 10/30= 28/30= 14/15= 1 1/15
2. 6/3 + 2/2 + 1/4= 24/12 + 12/12 + 3/12= 39/12 = 13/4 = 3 1/4

3. 6 1/3÷2 1/9= 19/3 ÷ 19/9= 171/57 = 57/19= 3/1 = 3

4. 2 7/9 ÷ 4/9= 25/9 ÷ 4/9= 225/36 = 6 9/36
