Solve the Expression: 0:-m/b+c with Given Variable Values

Let's start with the first option.

Let's substitute the given data into the expression:

$0:-\frac{3}{409}+8=$

We'll solve the exercise from left to right, noting that we are first dividing by zero.

Let's remember the rule:

$\frac{0}{a}=0$

In other words, any number divided by zero will equal zero, therefore:

$\frac{0}{-\frac{3}{409}}=0$

Now we got the exercise:

$0+8=8$

Let's continue with the second option.

Let's substitute the given data into the expression:

$0:-\frac{-\frac{1}{205}}{-7}+3004=$

As we can see, just like in the first option, we are first dividing by zero.

Any number divided by zero will equal zero, therefore we got the exercise:

$0+3004=3004$

Therefore the final answer is:

$1=8,2=3004$
