3.899 rounded to 2 decimal places is _____
Correct Answer 3.90 3.9
Explanation When rounding a number to 2 decimal places, we look at the digit in the third decimal place. If this digit is 5 or greater, we round up the second decimal place, and if it is less than 5, we leave the second decimal place as it is. In this case, the digit in the third decimal place is 9, which is greater than 5. Therefore, we round up the second decimal place to 0, resulting in 3.90. Additionally, 3.9 is also a valid answer as it is the rounded version of 3.899 to 1 decimal place.

If 2/3 = 8/x, what is x?
Correct Answer 12
Explanation The given equation states that the fraction 2/3 is equal to 8 divided by x. To find the value of x, we can cross multiply. By multiplying 2 and x, we get 2x, and by multiplying 3 and 8, we get 24. Therefore, the equation becomes 2x = 24. To isolate x, we divide both sides of the equation by 2, resulting in x = 12. Hence, the value of x is 12.
