Final answer:
The number 690 is 23% of 3000, which is determined by dividing 690 by 0.23.
Step-by-step explanation:
The student has asked what number 690 is 23% of. This can be solved by setting up a proportion where 23% (or 0.23 as a decimal) is set equal to 690 divided by some unknown number, which we can call X. So we have the equation 690 = 0.23 × X.
To solve for X, we need to divide both sides of the equation by 0.23. So we get X = 690 / 0.23. Performing the division gives us X = 3000. Therefore, 690 is 23% of 3000.
To find the number that 690 is 23% of, we can set up the equation: 690 = 0.23x, where x is the unknown number.
To solve for x, we divide both sides of the equation by 0.23: 690 / 0.23 = x.
Using a calculator, we find that x is approximately 3000. Therefore, 690 is 23% of 3000.
