We conclude that the value of k represented as a decimal rounded to the nearest tenth is: k = 16.8

Step-by-step explanation:

Given the expression

$\frac{5}{7}=\frac{12}{k}$

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.

Let us solve the expression

$\frac{5}{7}=\frac{12}{k}$

Apply cross-function multiply: if $\frac{a}{b}=\frac{c}{d}$ then $a\cdot \:d=b\cdot \:c$

$5k=7\cdot \:12$

5k=84 ∵ 7 · 12= 84

Divide both sides by 5

$\frac{5k}{5}=\frac{84}{5}$

Simplify

$k=\frac{84}{5}$

k = 16.8 (Rounded to the nearest 0.1 or the Tenths Place)

Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is: k = 16.8
