The cheap answer is, you simply "grab the denominator of one and multiply it times the other's top and bottom", so let's do so,

$\bf \cfrac{3}{5}\cdot \cfrac{4}{4}\implies \cfrac{12}{20}\qquad \qquad \qquad \qquad \qquad \cfrac{3}{4}\cdot \cfrac{5}{5}\implies \cfrac{15}{20}$

The shoe size for all the pairs of shoes in a person's closet are recorded.

Dovator [93]

The mean/average is found by adding all of your values and then dividing by the number of values found.

7+7+7+7+7+7+7+7+7+7=70

There are 10 size 7 shoes. Divide 70 by 10 to get the mean, which is 7.

Choose the correct simplification of m to the seventh power times n to the fourth power all over m to the fourth power times n t

Sholpan [36]

Answer:

$m^{3} n$

Step-by-step explanation:

Simplify $\frac{m^{7}n^{4}}{{m^{4}n^{3}}}$

We can simplify the expression by by using the quotient rule. Since the numerator is greater than the denominator and of similar terms, we'll subtract the denominator from numerator. This simply means that to divide two exponents with the same base, you keep the base and subtract the powers.

$=m^{7-4}n^{4-3}\\=m^3n$
