which numbers should i use to add to estimate the answer to 87,087 + 98,000
maybe try
87,000 and 98,000
86,000 + 100,000
Thanks you helped me on my homework
To estimate the answer to 87,087 + 98,000, you can use compatible numbers. Compatible numbers are numbers that are easy to work with mentally and still give an approximate result. In this case, we can round 87,087 to 90,000 and round 98,000 to 100,000.
By rounding both numbers up, we are overestimating the actual sum, so keep in mind that the result we obtain will be a little higher than the actual answer.
Now, we can add the rounded numbers together:
90,000 + 100,000 = 190,000
So, by using compatible numbers to estimate, we get the approximate sum of 87,087 + 98,000 as 190,000.
