Answer:
1
Explanation:
This question is basically asking us to round 0.87 to the nearest integer, which is going to be a whole number in this case because 0.87 is positive. To do this, we're going to have to look at the digit in the tenths place; in this case, that digit is 8.
Is 8 closer to 10 or 0? Well, it's obviously closer to 10. So, we're going to round 0.87 up, bringing us to 1.
If that's confusing or you need more clarification, let me know. :)
