There is no algebraic way of isolating X unfortunately.
For these equations, you have to solve with numerical approximation.
I suggest Newtons method if you know calculus.
The Greatest Common Factor of 32 and 48 is 16.
The longest necklace she can make is of 16 inches length.
#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply
