Let's use algebra to solve the problem.

Let the unknown number be x.

We know that 63 is 70% of x, so we can write the equation:

63 = 0.70x

To isolate x, we divide both sides of the equation by 0.70:

x = 63 / 0.70

Using a calculator, we find that x ≈ 90.

Therefore, sixty-three is 70% of the number 90.
