Hi this is my problem
23x12
23is close to 25
12is close to_
I think it's 10 -15
Than 25x10or15 = 250 or 375
23 is indeed closer to 25 than to 20
12 is closer to 10 than to 20 or even to 15
so 10 * 25 = 250 right
the real answer is 276 so not bad
25 * 15 = 375 which is not nearly as good
Thank u Damon
You are welcome.
If you're trying to approximate the product of 23 and 12, you can use the method you mentioned by approximating each number separately.
You mentioned that 23 is close to 25, which is correct. Now, to approximate 12, you suggested that it is close to a range of 10-15. Let's take the average of that range, which is 12.5.
So, now we have 25 for approximating 23 and 12.5 for approximating 12.
To find the product, you can simply multiply 25 by 12.5:
25 x 12.5 = 312.5
Therefore, the approximation of 23x12 is approximately 312.5. It is important to note that this is an estimation, and the actual exact value of 23x12 is 276.
Keep in mind that this method is a rough estimation and may not always give you an accurate result. In this case, the approximation is close but not exact.
