Answer:
Suppose 3 consecutive integers are X-1,X,X+1
Step-by-step explanation:
Sum = X-1+X+X+1= -78
3X=-78
X= -78/3
X= -26
3 consecutive integers are, -27, -26,-25.
smallest integer is -27

Answer:
A) 
B)
Step-by-step explanation:
To answer this question first we define what are rational numbers.
A rational number is a number that can be expressed in the form of a fraction
, where x and y are integers and y ≠ 0.
a) 0.12345
This can be written in fraction form as

Now, we simplify this fraction to lowest form. Simplified form of the above fraction is
. This simplified form was obtained by dividing both numerator an denominator by 5.
b) This number can be written in fraction form as 
Now, we simplify this fraction.
The simplified form of the above fraction is
as the numerator and denominator have no common factor.
Answer:
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w
