The second floor of a tiny house has a living room in a bedroom. The floor plan shows a width of 8 ft in a total length of 24 ft

Keith_Richards [23]

Answer:

Expression 8 • 24 represents the total area.

Option A is correct.

Step-by-step explanation:

Width of living room = 8 ft

Length of living room = 24 ft

We need to calculate area:

The formula used is: $Area=Length \times Width$

Putting values to get the expression

$Area = 8\times24$

So, Expression 8 • 24 represents the total area.

Option A is correct.

Answer:

$\displaystyle \frac{8}{18} = \frac{4}{9}\ ,\ \displaystyle \frac{12}{27} = \frac{4}{9}$

Step-by-step explanation:

<u>Equivalent Fractions</u>

Two fractions are equivalent if they represent the same rational number, regardless of their expression. For example, the fraction 2/5 is equivalent to 10/25 since they both represent the number 0.4

To find if a given fraction is equivalent to another given fraction, we can simplify or amplify it until an equivalence is found or not. We can also simply perform the division and compare the results.

We must find out if the four choices are equivalent to the fraction 4/9. Let's start with the first one

$\displaystyle \frac{20}{36} =\frac{5}{9}$

We simplified it by 4 and found it's not equivalent to 4/9. The fraction

$\displaystyle \frac{8}{18} = \frac{4}{9}$

is equivalent to 4/9 when simplified by 2.

$\displaystyle \frac{24}{45} = \frac{8}{15}$

This fraction was simplified by 3 and is not equivalent to 4/9. Finally

$\displaystyle \frac{12}{27} = \frac{4}{9}$

Is equivalent to 4/9 when simplified by 3. Summarizing, these fractions are equivalent to 4/9

$\boxed{\displaystyle \frac{8}{18} = \frac{4}{9}\ ,\ \displaystyle \frac{12}{27} = \frac{4}{9}}$

Rebecca drove 44 1/3 miles in 1 1/3 hours. What is the unit rate for miles per hour?

saul85 [17]

$unit\ rate=\frac{distance}{time}\\\\
distance=44\frac{1}{3} miles\\
time=1\frac{1}{3}hour\\\\
unit\ rate=\frac{44\frac{1}{3}}{1\frac{1}{3}}=\ \ \ | make\ improper\ fractions\\
\frac{\frac{133}{3}}{\frac{4}{3}}=\frac{133}{3}*\frac{3}{4}=\frac{133}{4}=33\frac{1}{4}\\\\
unit\ rate= 33\frac{1}{4}\frac{miles}{hour}
$
