This is done by factoring. 1/8 is smaller than 1/2, so we can factor a 1/8 out of 1/2. This is what that looks like:

, because factoring after all is a form of division. When we divide a fraction by a fraction, we bring the lower fraction up and flip it to multiply, giving us this:

. This of course reduces to 4. So when we factor out 1/8, what we will have then is

, choice D from above.

Answer:
C: 11.5 cm, 4.2 cm, 7.6 cm
Step-by-step explanation:
In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle
D. 3.1 +6.6 = 9.7 < 10.4
