✔ 最佳答案
=(2*16+6)/16+8/12+5/8
=38/16+8/12+5/8
L.c.m of 16, 12 and 8 is 48
so (3*38+4*8+6*5)/48
=(114+32+30)/48
=176/48
3.66

2 6/16 + 8/12 + 5/8
= 2 (6 x 3)/(16 x 3) + (8 x 4)/(12 x 4) + (5 x 6)/(8 x 6)
= 2 18/48 + 32/48 + 30/48
= 2 50/48 + 30/48
= 2 80/48
= 2 5/3
= 3 2/3

2 18/48 + 32/48 + 30/48
2 80/48
2 5/3
2 + 1⅔
3 ⅔

1+2\3=
3\3+2\3=
5\3
thanks for this question.
if you mean 26 not 6 in the first part then the solution :

2 6/16(multiply by2\2) +8/12 (multiply by4\4)+5/8=
13\8+2\3+5\8=
18\8(multiply by2\2)+2\3=
9\4+2\3=
(27+8)\12=
35\12

first you take lcm of 16,12 and 8. you'll get 24.
then multiply each fraction by 24
26/16*24+8/12*24+5/8*24
=39+16+15
=70
