Answer:
I am good at reading, but I am TERRIBLE at math..
The answer is 24.5 because

so you add 5.5 from 19 to get the answer
4’1= 4 feet and 1 inch
12 inches= 1 ft.
12(4)= 48 ; 48+ 1inch = 49 inches
1’10= 1 foot and 10 inches
1(12)= 12 + 10 = 22
49-22= 27 inches !
The only thing you need to do is divide 56 by -7. You know the d must be a negative number because negative x negative= positive. So 56 / -7 is -8.
The benchmarks are: 0, 0.25, 0.50, 0.75 and 1.
2. 81 → 2.75
+
3.73 → 3.75
------------
2.75 + 3.75 = 6.50
