5/9 + 8/9 = 13/9
not 13/18

It is
(5 + 8) * (1/9)

Disagree again

You said

What is the perimeter of a rectangle if the length is 7/11 ft and the width is 2/11ft?
Answer: 9/11 ft
***********************************
I say you need two times the length and 2 times the width
18/11 = 1 7/11

Disagree below

8/15 + 3/20
Answer: 11/35
*******************
I say
15 = 3*5
20 = 4*5
so we need 12*5 for denominator, in other words 60
24/60 + 9/60 = 33/60 = 11/20

The only answer(s) are

11/60
41/60
41/300
since it is not 11/35

1 3/8 + 4 ¾ + 2 1/6

Answer: 8 1/3
************************
I think
33/24 + 114/24 + 52/24 = 199/24
= 8 7/24

33/60 is not 11/60 but 11/20. I suspect a typo

0.76

Answer: 76/100
********************
true, but it can be simplified. Top and bottom are even numbers so at least divide both by 2
38/50 Oh, again by 2

19/25

19 is a prime number, no more factors
