There are two key terms in this question that we need to understand in order to answer the question correctly: product and prime numbers.

Product is the answer to a multiplication problem.

Prime numbers are numbers that are greater than and only have factors of the number and itself. For example is a prime number because it's greater than and the factors of are only and .

To find the correct answer, we need to know the factor pairs for our answer choices. The correct answer will have a factor pair of two prime numbers.

Let's look at our answer options:

- A factor pair for  is , and $\displaystyle 6$ is not a prime number.

$\displaystyle 50$- A factor pair for $\displaystyle 50$ is $\displaystyle 5\times10$. Though $\displaystyle 5$ is a prime number, $\displaystyle 10$ is not.

$\displaystyle 64$- A factor pair for $\displaystyle 64$ is $\displaystyle 8\times8$, and $\displaystyle 8$ is not a prime number.

$\displaystyle 34$- A factor pair for $\displaystyle 34$ is $\displaystyle 2\times17$. Both and $\displaystyle 17$ are prime numbers, thus $\displaystyle 34$ is our correct answer.

$\displaystyle 66$- A factor pair for $\displaystyle 66$ is $\displaystyle 6\times 11$, and $\displaystyle 6$ is not a prime number.  

$\displaystyle 88$- A factor pair for $\displaystyle 88$ is $\displaystyle 8\times11$, and $\displaystyle 8$ is not a prime number.

$\displaystyle 22$- A factor pair for $\displaystyle 22$ is $\displaystyle 2\times 11$. Both and $\displaystyle 11$ are prime numbers, thus $\displaystyle 22$ is our correct answer.

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{1}{2}\times\frac{4}{4}=\frac{4}{8}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{4}{8}>\frac{1}{8}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{3}{4}\times\frac{2}{2}=\frac{6}{8}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{6}{8}< \frac{7}{8}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{1}{2}\times\frac{6}{6}=\frac{6}{12}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{6}{12}=\frac{6}{12}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{5}{7}\times\frac{3}{3}=\frac{15}{21}$

$\displaystyle \frac{1}{3}\times\frac{7}{7}=\frac{7}{21}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{15}{21}>\frac{7}{21}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{2}{3}\times\frac{5}{5}=\frac{10}{15}$

$\displaystyle \frac{4}{5}\times\frac{3}{3}=\frac{12}{15}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{10}{15}< \frac{12}{15}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{1}{2}\times\frac{5}{5}=\frac{5}{10}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{5}{10}=\frac{5}{10}$

To compare fractions, we need to first make common denominators. 

$\displaystyle \frac{7}{8}\times\frac{5}{5}=\frac{35}{40}$

$\displaystyle \frac{2}{5}\times\frac{8}{8}=\frac{16}{40}$

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

$\displaystyle \frac{35}{40}>\frac{16}{40}$
