Reduce the following fraction: -32abc/64a^2bc^2

mafiozo [28]

Answer:

$-\dfrac{1}{2ac}$

Step-by-step explanation:

Given:

$\dfrac{-32abc}{64a^2bc^2}$

Reduce this fraction.

Work with numbers and different letters separately:

1. Numbers:

$\dfrac{-32}{64}=-\dfrac{32}{32\cdot 2}=-\dfrac{1}{2}$

2. Letter a:

$\dfrac{a}{a^2}=\dfrac{a}{a\cdot a}=\dfrac{1}{a}$

3. Letter b:

$\dfrac{b}b}=1$

4. Letter c:

$\dfrac{c}{c^2}=\dfrac{c}{c\cdot c}=\dfrac{1}{c}$

Hence,

$\dfrac{-32abc}{64a^2bc^2}=-\dfrac{1}{2}\cdot \dfrac{1}{a}\cdot \dfrac{1}{c}=-\dfrac{1}{2ac}$

How does the volume of a cone change if its radius and height are both tripled

Evgesh-ka [11]

The volume formula could be re-written to help understand this, as V = π*3r^2*3h. If you solve for this, you can conclude that the volume would be multiplied by 27.

Answer:

Step-by-step explanation:

Write down the expression exactly as it is given.

$\dfrac{3y - 9}{x} =$

Now write the expression again, but replace x with 3, and replace y with 6.

$= \dfrac{3 \times 6 - 9}{3}$

Now simplify the numerator using the correct order of operations.

$= \dfrac{18 - 9}{3}$

$= \dfrac{9}{3}$

Now divide 9 by 3.

$= 3$
