Answer:
Step-by-step explanation:
Well, this is a dumb problem... they're trying to trick you with the answers. :(
Okay, so what you're going to do is multiply the whole numbers by 1 put into the fractions.
Juan= 4 1/6--- 4 * 6/6 = 24/6
24/6 + 1/6 = 25/6
Antonio= 3 2/3 ---- 3 * 3/3 = 9/3
9/3 + 2/3 = 11/3
They changed the names around in the answers- Pay attention to who is associated to each fraction.
The right answer is D. Good luck... I hate it when problems try to trick you like that.

Answer:
You use the facts about a 30, 60, 90 triangle.
Step-by-step explanation:
The angles in a triangle add up to 180.
90+30+x=180
120+x=180
x=60
This is a 30-60-90 right triangle.
The side opposite the 30 degree angle is a.
The side opposite the 90 degree angle (hypotenuse) is 2a.
The side opposite the 60 degree angle is a
We know the side opposite the 90 degree angle.
2a = 12
Divide by 2.
a=6
a is the side opposite the 30 degree angle (y)
Because we know a, we can find a.
6
The square roots cancel, leaving 3.
6 times 3 is 18.
Therefore, the side opposite the 60 degree angle (x) is 18.
You have to add them the find the reciprocal and divided to find the width then turn it to a fraction them multiply and subtract again and find your answer
