1. Get the preceding sign out of the equation or at least infront of it:

411 ∗ 7

5 ∗ 5521 4

11 ∗ 75 ∗ 55

21

Negative times negative is positive and positive times negative

is negative. So you’ll end up with:

411 ∗ 7

5 ∗ 5521

Now you can reduce the fraction:

411 ∗ 7

5 ∗ 5521 41 ∗ 1

5 ∗ 53 41 ∗ 1

1 ∗ 13 4 ∗ 1 ∗ 1

1 ∗ 1 ∗ 3 43

To get to that, you can divide the 55 by 11, the 21 by 7 andthan the 5 by 5 (which you got by dividing the 55 by 11). But

bear in mind that you are reducing here and that works always

the same.

This only works with dividing and multiplying not adding or

subtracting!

And

So you are left with the improper fraction:

So you can divide 1 by 3 which is 0,3333333…, add it to the 1

and than make it negative because of the minus in front of all

of it:

,… , …

The same applies to b) but pay attention to the operators!

First divide and multiply than add and subtract!

Now, 2 left and 18.000€ to divide, that leaves 9.000€ per

leaving buyer, which is obviously also the amount of money each

of all 6 buyers would have to pay.

So, to get the total land price now is easy:

The equation they show to explain is correct but too

complicated to understand and solve the question. The best

thing is to stick to the plan and given numbers. Although,

maybe we just did their equations with words. :D
