Answer: Choice D) 8 & 1/8
This is read as "Eight and one-eighth"
======================================================
You want the perimeter so you'll add the three fractions to add up the three side lengths.
1/2 is the same as 4/8 (since 4 is half of 8). You can think of having a cake that is cut up into 8 equal slices. If you take 4 of those slices, then you take half of the cake.
So the value 3&1/2 is the same as 3&4/8. Similarly, 2&1/2 is equivalent to 2&4/8
We want to add the three mixed numbers: 2&1/8, 3&4/8, 2&4/8
Add up the fractional parts: 1/8+4/8+4/8 = (1+4+4)/8 = 9/8 = 1&1/8
The whole part '1' carries over to the other whole parts.
Add up the whole parts: 2+3+2 = 7
Then add in the carry: 7+1 = 8
Overall, the three numbers {2&1/8, 3&4/8, 2&4/8} add up to 8&1/8 which is the final answer (choice D)
