Answer 2

It appears that you've provided a list of equations, each with a percentage calculation. However, the format is not entirely clear. If you meant to express the equations as follows:

1. 17% of what number equals 68?
2. 11% of what number equals 33?
3. 23% of what number equals 138?

Then we can solve each equation as follows:

1. Let x be the unknown number. Equation: 17% of x = 68 To find x, we can set up the equation: 0.17x = 68 Now, solve for x: x = 68 / 0.17 ≈ 400

So, 17% of 400 is 68.

2. Let y be the unknown number. Equation: 11% of y = 33 To find y, we can set up the equation: 0.11y = 33 Now, solve for y: y = 33 / 0.11 = 300

So, 11% of 300 is 33.

3. Let z be the unknown number. Equation: 23% of z = 138 To find z, we can set up the equation: 0.23z = 138 Now, solve for z: z = 138 / 0.23 ≈ 600

So, 23% of 600 is 138.
