25 = 5*5 and 9 = 3*3, which we can exploit to write
so that this expression is actually a difference of squares. We can factorize this to get
and given that , we divide both sides by this to get
40% = 40 / 100 = 0.4
32 is 40% of what
= 32 / 40
= 32 / 0.4
= 80

U can also use this equation to solve it.
32 = 40%x
Simplfy
= 32 = 2/5x
Flib the equation.
2/5x = 32
Multipy both sides by 5/2
(5/2) * 2/5x = (5/2) * 32
x = 80.
