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}

geniusboy [140]

Answer:

B and F

Step-by-step explanation:

Equivalent expressions are expressions which in simplest form are equal. Simplify each expression to see each equals the simplest form of 12 - 14/3 t + 2/3 t.

12 - 14/3t + 2/3 t simplifies to 12 - 12/3t = 12 - 4t.

The options are:

a. 8t

b. 12-4t

c. -4(3 + t)  = -12 - 4t

d. 4(t - 3)  = 4t - 12

e. 12 - 16/3t

f. -4(t - 3) = -4t + 12

b and f are equivalent
