Answer:

A-3/4=1/8 is the equation, if you expand 3/4 it is 6/8, in order to get 1/8 you need to subtract 6/8 from 7/8

7/8-6/8=1/8 therefor A=7/8

The area of a rectangular patio is (12x - 4) square units. What are possible dimensions of the patio?

MAVERICK [17]

You need two terms that multiply to (12x-4). The term on the outside needs to be a common multiple of 12 and 4. The common factors are 1, 2, and 4. Here are the following possible dimensions:
1(12x-4)
2(6x-2)
4(3x-1)
Hope this helps.

Simple the expression <br> ( 3k + 4 1/5) + 8 3/5

lesantik [10]

Answer:

$3k+12\frac{4}{5}$

Step-by-step explanation:

$(3k+12\frac{4}{5})$

Convert mixed numbers to improper fractions:

$a\frac{b}{c}=\frac{a*c+b}{c}$

$4\frac{1}{5}=\frac{4*5+1}{5}$

$=\frac{21}{5}$

$=(3k+\frac{21}{5} )+\frac{43}{5}$

Add the fractions

$\frac{21}{5}+\frac{43}{5}$

$\frac{21}{5} \frac{43}{5} =\frac{64}{5}$

$=3k+\frac{64}{5}$

Divide 64 by 5

$\frac{64}{5}$ $12.8 or 12\frac{4}{5}$

$=3k+12\frac{4}{5}$

What does 5 over 100 =

Nuetrik [128]

You can identify that "5 over 100" can be written as a fraction. 5 will be the numerator and 100 will be the denominator:

$\frac{5}{100}$

To reduce this fraction, you need to divide the numerator and the denominator by the Greatest Common Factor (GCF) between them.

In this case, to find the GCF, you need to:

- Decompose the number into their Prime Factors:

$\begin{gathered} 5=5 \\ 100=2\cdot2\cdot5\cdot5=2^2\cdot5^2 \end{gathered}$

- Notice that 5 is a common factor. Then, you need to choose the one with the lowest exponent:

$GCF=5$

Therefore, by dividing the numerator and the denominator by 5, you get:

$=\frac{1}{20}$

Hence, the answer is:

$=\frac{1}{20}$
