What is your answer?
R.I.P Ms. Sue, thank you for your help all these years.
To mentally estimate 49% of 162, you can follow these steps:
1. Start by recognizing that finding 50% of a number is the same as finding half of it. In this case, half of 162 is 81.
2. Now, since you need to estimate 49%, which is 1% less than 50%, you can subtract 1% of 162 from the answer you obtained in step 1.
3. To find 1% of a number, you divide it by 100. So, dividing 162 by 100 gives you 1.62.
4. Now, subtracting 1.62 from 81 will give you an estimate of 49% of 162.
Calculating step by step:
81 - 1.62 = 79.38
Therefore, using mental math, 49% of 162 is approximately 79.38.
