Resposta:

a)5/8+1/4+5/12= 31/24

b)7/6-1/3+5/6= 5/3

c)2/5+1= 7/5

d)2-3/4= 5/4

Explicação passo-a-passo:

a)5/8+1/4+5/12= 5x3 + 1x6 + 5x2 / 24 = 15+6+10 / 24 = 31/24

b)7/6-1/3+5/6= 7x1 - 1x2 + 5x1 / 6 = 7-2+5 / 6 = 10/6 = 5/3

c)2/5+1= 2x1 + 1x5 / 5 = 2+5 = 7/5

d)2-3/4= 2x4 - 3x1 / 4 = 8-3 / 4 = 5/4
