When 2 even numbers are added, the sum is even. (Even + Even = Even)
When 2 odd numbers are added, the sum is even. (Odd + Odd = Even)
When 1 odd and 1 even number are added, the sum is odd. (Odd + Even = Odd)
Will rounding to the nearest 10 or the nearest 100 give a closer estimate of 748−431748-431 ? Explain your answer. (4 points)
Rounding to the nearest 10 will give a closer estimate of 748 - 431 compared to rounding to the nearest 100.
To understand why, let's look at the numbers being rounded.
748 rounded to the nearest 10 is 750.
431 rounded to the nearest 10 is 430.
So, when we subtract 430 from 750, the result is 320.
On the other hand, if we were to round 748 and 431 to the nearest 100, we would get:
748 rounded to the nearest 100 is 700.
431 rounded to the nearest 100 is 400.
Subtracting 400 from 700 gives us 300.
Therefore, rounding to the nearest 10 gives us a closer estimate of 748 - 431 compared to rounding to the nearest 100, as the result is only 20 away from the actual answer, while rounding to the nearest 100 gives us a result that is 100 away from the actual answer.
