Answer :

To solve for [tex]\( k \)[/tex] in the equation

[tex]\[ \frac{12}{7} = \frac{k}{8} \][/tex]

we need to use a method known as cross-multiplication, which allows us to solve the proportion by eliminating the fractions.

Here are the steps to solve for [tex]\( k \)[/tex]:

1. Set up the equation:

[tex]\[ \frac{12}{7} = \frac{k}{8} \][/tex]

2. Cross-multiply:
This means we multiply the numerator of one fraction by the denominator of the other fraction. Specifically, multiply 12 by 8 and 7 by [tex]\( k \)[/tex]:

[tex]\[ 12 \cdot 8 = 7 \cdot k \][/tex]

3. Perform the multiplication:

[tex]\[ 96 = 7k \][/tex]

4. Isolate [tex]\( k \)[/tex]:
To solve for [tex]\( k \)[/tex], divide both sides of the equation by 7:

[tex]\[ k = \frac{96}{7} \][/tex]

5. Simplify the fraction:
Finally, perform the division to get the numerical value of [tex]\( k \)[/tex]:

[tex]\[ k = 13.714285714285714 \][/tex]

Therefore, the value of [tex]\( k \)[/tex] is approximately [tex]\( 13.714285714285714 \)[/tex].
