Can (8 / 7 + 16 / 3) be divided by 16 / 13

(8/7+16/3)÷16/13
8/7÷16/13+16/3÷16/13
=13/14+13/3

I don't know if it's a simple operation

5 / 16 * [(10-350%) divided by 13 / 2] divided by 8 / 5

5 / 16 * [(10-350%) divided by 13 / 2] divided by 8 / 5
=5/16*(13/2*2/13)*5/8
=5/16*5/8
=1/2

() divided by 5 / 6-16 / 7 * 7 / 8 = 28 1 divided by (4 / 5 * () - 1 / 5) = 3

（ ）÷5/6-16/7*7/8=28
（ ）÷5/6-2=28
（ ）÷5/6=28+2=30
（ ）=30×（5/6）
（ ）=25
1÷（4/5*（ ）-1/5）=3
4/5*（ ）-1/5=1÷3=1/3
4/5*（ ）=1/3+1/5=8/15
（ ）=(8/15)÷(4/5)
（ ）=2/3
