The correct answer is $\frac{1}{5}$
There are $65$ cards in the bag and $13$ of them are white. Then, $13$ out of $65$ cards are white. You can write this as: $\frac{13}{65}$. To simplify this fraction, divide both numerator and denominator by $13$. Then:
$\frac{13}{65}=\frac{1}{5}$

The correct answer is $3 \ ÷ \ 11$
$\frac{3}{11}$ means $3$ is divided by $11$.
The fraction line simply means division or $÷$.
Therefore, we can write $\frac{3}{11}$ as $3 \ ÷ \ 11$.

The correct answer is $A \ + \ 20=40$ 
Plug in $20$ for $A$ in the equations.
Only option $A$ works.
$A \ + \ 20=40$
$20 \ + \ 20=40$

The correct answer is $8$ hours and $30$ minutes
$50$ miles : $1$ hour
$425$ miles : $425 \ ÷ \ 50 = 8.5$ hours

The correct answer is $125\%$
Use percent formula:
part $= \frac{percent}{100} \ ×$ whole
$50 = \frac{percent}{100} \ × 40 ⇒$
$50 = \frac{percent \ × \ 40}{100} ⇒$
$50 =\frac{percent \ × \ 4}{10}$, multiply both sides by $10$.
$500 =$ percent $× \ 4$, divide both sides by $4$.
$125 =$ percent

The correct answer is $104$
First, find the missing side of the trapezoid.
The perimeter of the trapezoid below is $52$.
Therefore, the missing side of the trapezoid (its height) is:
$52 \ - \ 12 \ - \ 18 \ - \ 14=52 \ - \ 44=8$
Area of a trapezoid:
A $= \frac{1}{2} \ h (b_{1} \ + \ b_{2}) = \frac{1}{2} \ (8) \ (12 \ + \ 14) = 104$
