Answer:
-3/2
Step-by-step explanation:
In the picture attached, the complete question is shown.
The expression is:
You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:
The addition of a negative fraction is simply the subtraction by that fraction:
Which can be simplified dividing by two both numerator and denominator:
Set up the proportion with the numbers on top equalling the cars and the numbers on the bottom representing the trucks.
c equals the number of unknown cars.
To solve the proportion, cross multiply (multiply 8 by 9 and 36 by c) and solve for c.
72 = 36c
Divide 36 from both sides to get the answer.
c = 2
If there are 9 trucks, there are 2 cars.
You can check this by dividing 2 by 9, and dividing 8 by 36. Since they both equal the same number, this answer is correct.
Hope this helps =)
