How about 13 out of 16 times 5 plus 5 out of 16 times 19

How about 13 out of 16 times 5 plus 5 out of 16 times 19

13 out of 16 times 5 plus 5 out of 16 times 19
=13/16×5+5/16×19
=5/16×13+5/16×19
=5/16×（13+19）
=5/16×32
=10

14 out of 19 minus 5 out of 13 plus 5 out of 19 minus 8 out of 13

14/19-5/13+5/19-8/13= 14/19 +5/19 -（5/13+ 8/13）=1-1=0

8:3-0.35 + (1:1-6:13)

8:3-0.35 + (1:1-6:13)
=35/4-35/100+(5/4-133/20)
=35(25-1)/100+(25-133)/20
=7*12/10-54/10=3

(5 and 2 / 5-1.8) / [(1.15 + 13 / 20) * 1 and 2 / 3] and

(2 / 5-1.8) / [(1.15 + 13 / 20) * 2 / 3]
=（5.4-1.8）÷[(1.15+0.65)x5/3]
=3.6÷（1.8x5/3）
=3.6÷3
=1.2
