What is the distance around a triangle that has sides measuring 2 1/8 feet, 3 1/2 feet, and 2 1/2 feet? a- 7 1/8 feet b- 7 9/24 feet c- 8 feet d- 8 1/8 (show work pleae! ^v^)

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)
