STEP 1:
Add the number of total students
= 27+25+23
=75
STEP 2:
Find the percentage that 18 out of 75 students is.
18/75=x/100
cross multiply
(18*100)=(75*x)
1800=75x
divide both sides by 75
24%=x
Check:
75 * 24%= 18
Hope this helps! :) Good luck!
50 *0.4 = 20 tables seat 2
50-20 = 30 tables seat 4
30*4 = 120
20*2 =40
120 +40 = 160 seats total
By clearing my brain and tuning my sensitive being to the waves of the immutable spheres, I have succeded in detecting the emanations of your innermost thoughts. I can see that you are thinking of the numbers '2' and '4'.
The expression is not equivalent because when you test x with any number besides 8 you get two different answers
