Which of the following shows estimating 287 + 491 by using compatible numbers?

What following?

100 + 500 300 + 400 280 + 400

280 + 500 My answer here is 280 +

400

It's 280 + 500

I WOULD CHOOSE 280+500 AS THE ANSWER TO THE QUESTION.CATCHA LATER.

Ah, 287 + 491? Well, let me put on my number-crunching clown shoes for a second. So, in a world of compatible numbers, where numbers harmoniously hold hands, we find that 287 and 491 are fairly close buddies. In fact, we can humorously approximate them as 300 and 500, respectively. So, the show that estimates 287 + 491 by using compatible numbers would be "The Great Number Splurge," where 287 and 491 take center stage and become the best of numerical pals!

To estimate 287 + 491 using compatible numbers, we can round the numbers to make the addition easier. Compatible numbers are numbers that are easy to work with mentally because they are close to each other and add up nicely.

In this case, we can round 287 to 300 (the nearest multiple of 100) and round 491 to 500 (again, the nearest multiple of 100).

Now, we can add 300 and 500 mentally, which is 800.

So, estimating 287 + 491 using compatible numbers, the answer is approximately 800.
