Question

1. $0.6y = -12$
2. $\frac{3}{4}n = 6$
3. $-8.6w = -365.5$
4. $2\frac{1}{2}x = 22\frac{1}{2}$

Explanation:

Step1: Isolate $y$ by dividing by 0.6

$y = \frac{-12}{0.6}$

Step2: Calculate the value of $y$

$y = -20$

Step1: Isolate $n$ by multiplying by $\frac{4}{3}$

$n = 6 \times \frac{4}{3}$

Step2: Calculate the value of $n$

$n = 8$

Step1: Isolate $w$ by dividing by $-8.6$

$w = \frac{-365.5}{-8.6}$

Step2: Calculate the value of $w$

$w = 42.5$

Step1: Convert mixed numbers to improper fractions

$2\frac{1}{2} = \frac{5}{2}$, $22\frac{1}{2} = \frac{45}{2}$

Step2: Isolate $x$ by multiplying by $\frac{2}{5}$

$x = \frac{45}{2} \times \frac{2}{5}$

Step3: Calculate the value of $x$

$x = 9$

Answer:

1. $y = -20$
2. $n = 8$
3. $w = 42.5$
4. $x = 9$
