Translate the following problems into algebraic equations :
1- What number is 15% of 108?
x = 0.15*108
------------------------
2- 16 is what percent of 54?
16 = 54(x/100
------------------------)
3- The sum of three consecutive even numbers is 144; what are the numbers?
2x + (2x+2) + (2x+4) = 144
============================

(1) x+=+.15%2A108
(2) 16+=+%28x%2F100%29%2A54
(3) 2n+%2B+%282n+%2B+2%29+%2B+%282n+%2B+4%29++=+144
Note that using 2n instead of n will guarantee that the numbers
will be even

1- What number is 15% of 108? Ans ...108x15/100= 16.20 %
2- 16 is what percent of 54? =(16/54)x100=1600/54=800/27=29.63 %
3- The sum of three consecutive even numbers is 144; what are the numbers?
let the mid no =n
numbers are
n-2
n
n+2
add
3n=144
n=144/3=48
numbers are 46, 48 and 50
bravo
