Answer:
To find the number that 68 is 40% of, we can set up the following equation:
40% of x = 68
To solve for x, we can divide both sides of the equation by 40% (or 0.4) to isolate x:
x = 68 / 0.4
Evaluating the expression on the right side of the equation gives us:
x = 170
Therefore, 68 is 40% of 170.
