Respuesta :
1/2x
the reason why is cuz if 80% of a # is x, and 40% is 1/2 of 80%, than 40% must be 1/2x

80% of a number is x
so let us say the number is y
that means 80 % of y is x.
Making an equation we have,
[tex] 0.08 y = x [/tex]
So solving for y we have,
[tex] y =12.5x [/tex]
Now we have to find what is 40 % of the number.
So we have to find 40 % of y here
0.04 *y = 0.04 (12.5 x)
y=1.5 x
So we can say that 40 % of the number is 1.5 x
