Yes I think that is correct
The equation is
.
1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)
The new equation is
. Subtract the numerators.
17 - 4 = 13 or 13/8
The improper fraction
simplifies to
.

Problem
Is 4.55 and 1.23456 a rational number
Solution
4.55 can be written as:
455/100 so then it could be a rational number
For the second number we have: 1.23456
And we can write this number as:
123456/100000
So then is also ratioanl
((b1+b2)÷2)(h)=A
so I think the answer is 3 1/16 or 3.0625
