Explicação passo-a-passo:
((1/8+1/5)÷(2/6+1/16))+0,125=
(1/8+1/5)÷(2/6+1/16)+0,125
1/8+1/5
5+8/40
13/40
(1/8+1/5)÷(2/6+1/16)+0,125
13/40÷(2/5+1/16)+0,125
(1/8+1/5)÷(2/6+1/16)+0,125
(2/6+1/16)
2/6+1/16 risque o numero 6
3/1+1/16
16+3/48
19/48
(1/8+1/5)÷(2/6+1/16)+0,125
13/40÷19/48+0,125
(1/8+1/5)÷(2/6+1/16)+0,125
0,125

((1/8 + 1/5) : (2/6 + 1/6) + 0,125
(1/8 + 1/5) ÷ (2/6 + 1/6) + 0,125
1/8 + 1/5
5+8/40
13/40
(1/8 + 1/5) ÷ (2/6 + 1/16) + 0,125
13/40 ÷ (2/6 + 1/16) + 0,125
(1/8 + 1/5) ÷ (2/6 + 1/6) + 0,125
2/6 + 1/6 aqui risque os dois numeros 2 e 6.
1/3 + 1/16
16+3/48
19/48
(1/8 + 1/5) ÷ (2/6 + 1/16) + 0,125
13/40 ÷ 19/48 + 0,125
(1/8 + 1/5) ÷ (2/6 + 1/16) + 0,125
0,125
125/1000
125/1000 aqui risque o numero 1000.
1/8
(1/8 + 1/5) ÷ (2/6 + 1/16) + 0,125
13/40 ÷ 19/48 + 1/8
13/40 × 48/19 + 1/8
13/40 × 48/19 + 1/8aqui risque os dois numeros 40 e 48.
13/5 × 6/19 + 1/8
13/5 × 6/19
13×6/5×19
78/5×19
13×6/5×19
