To solve this problem, we should set up an equation. To do this, we need to use our knowledge that the word "is" refers to an equals sign in algebraic expressions, and the word "of" refers to the operation of multiplication. Next, we need to convert 8% to its decimal equivalent, by dividing 8/100 (because percentages represent parts of 100 total percent).

8/100 = 0.08

Now, we can set up our equation, letting x represent our unknown value.

70 is 8% of a number

70 = 0.08x

To solve this equation, we need to divide both sides of the equation by 0.08 to get the variable x alone on the right side of the equation.

x = 875

Therefore, the answer is 875.

Hope this helps!
