Step-by-step explanation:
To multiply fractions, you just multiply across so you'd do:
3 × 2 = 6
4 × 3 = 12
The answer is 6/12, but it asks for the simplest form so you can simplify to 1/2. I hope this helps!

Step-by-step explanation:
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
