Lets say you have 5x5. you would just add 5+5+5+5+5. To get a whole number for a fraction you have to do this. lets say you have 8/8 that would be equal to 8 circles and eight of those circles would be shaded in. 8/8 is one whole also 7/1 is a whole. It all depends on the problem you are trying to figure out

Multiplication is the same as repeated addition so let us take an example for a better understanding

2/3 * 4

Looks more like this  

2/3 + 2/3 +2/3 = 2/3 = 8 /3  

(If you add them up, we will get the same answer if we multiply it)

Same as 2/3 *4/1 = 8/3  

On the other hand if you have whole numbers that you need to solve like 3*4 this means that 3 is added 4 times  

3 + 3+ 3+ 3 = 12

Which would be the same thing as  

3*4 = 12

1- Solution using graphs:
Take a look at the attached images.
The red graph represents the first given function while the blue graph represents the second given function.
We can note that the two graphs are the same line (they overlap).
This means that any chosen point on one of them will satisfy the other.
This means that there are infinite number of solutions to these two equations.

2- Solution using substitution:
The first given equation is:
y = -5x + 3 ...........> equation I
The second given equation is:
2y + 10x = 6 ...........> equation II

Substitute with I in II and solve as follows:
2(-5x+3) + 10x = 6
-10x + 6 + 10x = 6
0 = 0
This means that there are infinitely many solutions to the given system of equations.

Hope this helps :)

Answer:

6 511 104 in³

Step-by-step explanation:

Since we have 1 crate and 8 boxes fit into one crate.

So, volume of one crate, V' = 8 × volume of 1 box, V

Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.

So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³

So, V' = 8 × 813 888 in³ = 6 511 104 in³

So, the minimum volume of the crate is 6 511 104 in³
