Answer:

168000

Step-by-step explanation:

5/14 to the son.

that leaves 9/14 of the total.

these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.

how do we do that ?

well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).

but in general by multiplying. so 2/3 of 8/14 is

9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14

and then little surprising 1/3 is

9/14 × 1/3 = 9 / 14×3 = 3/14

now, we know, these 3/14 are 36000.

what we need to know is how much is 14/14 or 1/1 : the whole amount.

well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).

it in total, multiply it with the reverse fraction : 14/3

36000 × 14/3 = 12000×14 = 168000

\frac{24z^{5}y^{4}}{3z^{-2}y^{5}} = \frac{24}{3}*\frac{z^{5}}{z^{-2}}*\frac{y^{4}}{y^{5}} = \frac{8}{1} *\frac{z^{5+2}}{1}*\frac{1}{y^{5-4}} = \frac{8z^{7} }{y}

11)

(a²b)³ = a²⁽³⁾b¹⁽³⁾ = a⁶b³

12)

The exponent tells you how many places to move the decimal. The positive/negative sign tells you which direction to move the decimal (negative is left, positive is right).

8.4 x 10⁻⁵ <em>move the decimal 5 places to the left</em>   =  0.000084

Amber can peel 10 1/2 potatoes in 1/3 of an hour. What is her unite rate
Alexxx [7]

Given that:

- Amber can peel this amount of potatoes:

10\frac{1}{2}\text{ }potatoes

- And she can peel them in this time:

\frac{1}{3}\text{ }hour

You can determine that the Unit Rate is the number of potatoes she can peel per hour.

Since the number of potatoes is given as a Mixed Number, you can convert it to an Improper Fraction as follows:

1. Multiply the Whole Number part by the denominator.

2. Add the Product to the numerator.

3. The denominator does not change.

Then:

10\frac{1}{2}=\frac{(10\cdot2)+1}{2}=\frac{20+1}{2}=\frac{21}{2}

Now you can set up that:

Unit\text{ }Rate=\frac{\frac{21}{2}\text{ }potatoes}{\frac{1}{3}\text{ }hour}

Solving the Division, you get:

\begin{gathered} Unit\text{ }Rate=\frac{21\cdot3}{2\cdot1}\frac{potatoes}{hour} \\  \\ Unit\text{ }Rate=\frac{63}{2}\frac{potatoes}{hour} \end{gathered}

Hence, the answer is:

Unit\text{ }Rate=\frac{63}{2}\frac{potatoes}{hour}
