Question

1\2+1/5+1/7 3/4+5/12+1/3

Answer 1

1/2  +  1/5  +  1/7 =(1 × 35  +  1 × 14  +  1 × 10)/70 = 35/70  +  14/70  +  10/70 =  59/70
3/4  +  5/12  +  1/3=(3 × 3  +  5 × 1  +  1 × 4)/12 = 9/12  +  5/12  +  4/12 =  18/12 = 3/2 = 1 1/2

Answer 2

1/2 + 1/5 + 1/7
(35+14+10)/70 = 59/70

3/4 + 5/12 + 1/3
(9+5+4)/12=18/12 =3/2 =1.5
