Check the following that could be applied to percent estimation for the following problem: 27% of 125
- A.
- B.
- C.
- D.
Correct Answer(s)
A.
B.

Explanation
Percent estimation involves approximating the value of a percentage without the need for precise calculations. In this case, to estimate 27% of 125, one could round 27% to 25% and calculate 25% of 125, which is 31.25. Since 27% is slightly higher than 25%, the estimated value would be slightly higher than 31.25. Therefore, the answer is 31.

Correct Answer
A. Percent Estimation

Explanation
The correct answer is "Percent Estimation" because in this question, we are given the percentage of people in a certain age group who gave up their home phone and only use a cell phone. We are also given the actual number of people who only use a cell phone. To determine the total number of people surveyed, we can use percent estimation by estimating the percentage of the total population represented by the given number of people who only use a cell phone.

Using percent Proportion, check all the ways this problem can best be represented. What number is 25% of 180?
- A.
- B.
- C.
- D.
Correct Answer
A.

Explanation
To find what number is 25% of 180, we can set up a proportion using the percent proportion formula. The formula states that the part over the whole is equal to the percent over 100. In this case, the part is the unknown number we are trying to find, the whole is 180, and the percent is 25. Setting up the proportion, we get x/180 = 25/100. Cross-multiplying, we get 100x = 180 * 25. Solving for x, we find that x = 45. Therefore, 45 is 25% of 180.

40% of what number is 82?
- A.
  
  206
- B.
  
  210
- C.
  
  310
- D.
  
  205
Correct Answer
D. 205

Explanation
To find 40% of a number, we can multiply the number by 0.4. So, if we let the number be x, we have the equation 0.4x = 82. Dividing both sides by 0.4, we find that x = 205. Therefore, 40% of 205 is 82.
