You know that a number divided by itself is 1, so this is

$\dfrac{7^{-1}\times 7^{-7}}{7^{-7}}=7^{-1}\times\left(\dfrac{7^{-7}}{7^{-7}}\right)\\\\=7^{-1}\times 1=7^{-1}=\bf{\dfrac{1}{7}}$

Something to a negative power is the reciprocal of that thing to the opposite positive power.

Let the number be x.
0.75 % * x = 10
0.75/100 * x = 10
0.0075 * x = 10
x = 10/0.0075 = 1333.33
