A city has a population of 38,802,500 people. Estimate this population to the nearest ten million. Rounded to the nearest ten million, the population is about

40,000,000

Step-by-step explanation:

If you look at the 10 millionth place by itself, it's just 38. Now look at 8 by itself. Remember this rule: 1-4 round down, 5-9 go to town. Since 8 is in the range of 5-9, round up. Look at 38 again. The nearest 10th would be 40, hence 40,000,000 as the answer.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
