$\\ 20. \: \: ( \frac{ - 3}{4} )(4\frac{1}{6} )$

$\\ = \frac{ - 3}{4} \times \frac{25}{6}$

$\\ = \frac{ - 25}{8}$

$\\ = - 3.125$

$\\ 21. \: \: ( - 3\frac{7}{8} )( - 5\frac{3}{4} )$

$\\ = \frac{ - 31}{8} \times \frac{ - 23}{4}$

$\\ = \frac{713}{32}$

$\\ = 22.28125$

Answer 2. Ella was born early in the morning on a Monday. She got married on the 9074th day of her life. What day of the week wa

m_a_m_a [10]

Answer:

Ella got married on a Wednesday.

Step-by-step explanation:

Let's solve this problem by understanding the following:

Each week is composed by 7 days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

So 1 week = 7 days;

Because the married day was on the 9074th day of her life, we can find the number of weeks that 9074 days represent:

$\frac{1 week}{7 days} * 9074 days = 1296.285714 weeks$

This means that 9074 days represent 1296.285714 weeks, which can be interpreted as 1296 entire weeks and a fraction of a week (0.285714).

Now let's calculate how many days 0.285714 weeks represent:

$\frac{7 days}{1 week} * 0.285714 weeks = 2 days$

This means that 9074 days are actually 1296 weeks and 2 days, because Ella was born on a Monday, and because after 7 days (1 week) it is Monday again, after 1296 weeks it is Monday, but as we also calculated 2 extra days, then the married day is two days after a Monday, that is a Wednesday.

In conclusion, Ella got married on a Wednesday.
