is in proportion.
Step-by-step explanation:
The first example is and it is in proportion.
This is because, you will get the same simplest fraction (
) from the fraction 
by dividing its numerator and denominator by 5.
The second example is and it is not in proportion.
This is because, you can not get the simplest fraction (
) from the fraction 
after simplification.
The third example is and it is in proportion.
This is because, you will get the same simplest fraction (
) from the fraction 
by dividing its numerator and denominator by 2 and from the fraction 
by dividing its numerator and denominator by 3.
The fourth example is and it is in proportion.
This is because, you will get the same simplest fraction () from the fraction 
by dividing its numerator and denominator by 5. (Answer)
-1. Plug in -3 for x which makes 9-10 so -1
Answer:
x=5
Step-by-step explanation:
Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did
8-6*5=-22
And them I said let me see if any multiples equal -18 so I went to for and did this
8-6*4=-16
That's when I guessed the answer if i looked at the sign correctly!
