Help! I will answer, but want to make sure I'm right.
Enter your answer and show all the steps that you use to solve this problem in the space provided.
a) Estimate 49% of 162.
b) Use mental math to calculate 49% of 162.
To solve A I will round 49% to 50% and 162 to 150.
I have a question. Is the answer 3 because 50 goes into 150 3 times?
Also, how would I solve 49% of 162 IN MY HEAD?!?!
Help! Please! Quickly!
Thanks.
Clearly the answer is not 3.
50% is 1/2
So, you want 1/2 of 150.
If you thought you should divide, you're just guessing.
50% = .5 = 1/2
1/2 of 160 = 80
Use mental math to calculate 49% of 162. Showing steps
Sure, here are the steps to calculate 49% of 162 in your head:
1. Find 1% of 162 by dividing it by 100: 162 ÷ 100 = 1.62
2. Since you need to find 49%, you can multiply 1% by 49: 1.62 × 49 = 79.38
3. Round the answer to the nearest whole number: 79.38 ≈ 79
Therefore, 49% of 162 is approximately 79.
To estimate 49% of 162, you can round 49% to 50% and 162 to 150.
a) Multiply 50% (0.5) by 150 to get the estimate: 0.5 x 150 = 75. Therefore, the estimated answer is 75.
For mental math calculation, you can use the fact that 1% is equal to 1/100. Here's how you can solve it in your head:
b) To find 49%, first find 1% by dividing 162 by 100: 162 ÷ 100 = 1.62.
Then multiply 1.62 by 49 (which is 100/2 - 1): 1.62 x 49 = 79.38.
So, the answer to 49% of 162, calculated mentally, is approximately 79.38.
Remember, mental math requires practice and familiarity with various strategies and number relationships. It can be helpful to break down the problem into smaller, more manageable steps.
