Answer:

When dividing fractions, you must have the fractions in a/b form, you must flip the second fraction, then you must change the division sign to multiplication.

To solve the first problem, 1/2 ÷ 3/4, here are the steps:

Step 1: Make sure both fractions are in a/b form, in this case they are

Step 2: Flip the second fraction: so basically we're turning 3/4 into 4/3

Step 3: Change the division sign to multiplication

Step 4: Solve

1/2 • 4/3 = 4/6 = 2/3

To solve the second problem, follow these steps

Step 1: Make sure both fractions are in a/b form, we need to turn 1 1/3 into the improper fraction 4/3. The second fraction does not need to be changed because it is already in a/b form

Step 2: Multiply Across:

4/3 • 3/4 = 12/12 = 1

Step-by-step explanation:

I hope this helps!

The surface are I cannot find

check the picture below.

so the triangular prism is really just 3 rectangles and 2 right-triangles,

now, we know the base of one of the triangles is 2.6, what's its height?

since it's a right-triangle, we can simply use the pythagorean theorem to get "h".

$\bf \textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b
\qquad
\begin{cases}
c=\stackrel{hypotenuse}{5.2}\\
a=\stackrel{adjacent}{2.6}\\
b=\stackrel{opposite}{h}\\
\end{cases}
\\\\\\
\sqrt{5.2^2-2.6^2}=h\implies 4.5\approx h$

so, we can now, simply get the area of both of the triangles and the three rectangles and sum them up, and that's the area of the triangular prism.

$\bf \stackrel{two~triangles}{2\left[ \cfrac{1}{2}(2.6)(4.5) \right]}~~+~~\stackrel{rectangle}{(2.6\cdot 4.3)}~~+~~\stackrel{rectangle}{(4.3\cdot 3.9)}~~+~~\stackrel{rectangle}{(4.3\cdot 5.2)}
\\\\\\
11.7+11.18+22.36\implies \blacktriangleright 45.24 \blacktriangleleft$
