The solution has a positive answer (True).
<h3>What is the solution to the arithmetic operators and fractions?</h3>
Arithmetic operators are those signs such as addition, subtraction, multiplication, and division that are used to solve mathematical expressions such as fractions and linear equations.
1.
The solution to the expression:
= (-1)(1)(-1)(-1)(1)(-1)(-1)(-1)(-1)(1)(-1)(1)
= 1
Thus, the solution has a positive answer(True)
2.
The solution to the improper fraction:
3.
= -52.31 -(-7.44)
= -52.31 + 7.44
= -44.87
= - 4487/100
4.
The solution to the improper fraction is:
5.
The given equation is:
-(-6.6) (-20) = 132 which is incorrect.
The correct solution is:
-(-6.6) (-20) = -132
Eric's mistake is that he forgot to multiply by -1 first.

3. Is going to be 7*12= 84 inches because the tree is drawn as 7 inches in the scale and for every inch in the scale, it is 12 inches in real life.
4. Is going to be similar since for every inch on the map the meter in real life is 30 so 2.5*30= 74 meters.
Hope I explained it enough that you understand the concept and not just gave you an answer.
