A fraction is just a short way to WRITE a division problem. It means "the top number divided by the bottom number". Take the two numbers from the fraction, DO the division, and you get the decimal.
3x=4
To get x by itself, you need to divide 3 on both sides.
Your answer in fraction form:4/3
Your answer in decimal form:1.3

Answer:
36 Teachers in Total
Step-by-step explanation:
I would use Ratio.
Students: 128 + 121 + 135 = 384 total students
Teachers: Students
3 : 32
36 : 384
384 ÷ 32 = 12
12 x 3 = 36
The objective is to get the variable (x) alone. To do this start be subtracting 3. What you do to one side you have to do to the other so you have to subtract three from the other side of the equal sign as well. So now you have:
20x= 17-3 subtract the 3 to get 20x=14
Now because the 20 is attached to the x In order to get the x alone you have to divide by 20:
20x/20. =14/20 divide 14 by 20
X=.7 or x=7/10
