Answer:
2.99 = 3
2.999 = 3
Explanation:
To round 2.99 to the nearest tenth consider the hundredths’ value of 2.99, which is 9 and equal or more than 5. Therefore, the tenths value of 2.99 increases by 1 to 0.
2.99 rounded to the nearest tenth = 3.0
Now
To round 2.999 to the nearest hundredth consider the thousandths’ value of 2.999, which is 9 and equal or more than 5. Therefore, the hundredths value of 2.999 increases by 1 to 0.
2.999 rounded to the nearest hundredth = 3.00
So, If you would round it to the nearest tenth which is the third nine, you'd see that it would add up to the whole number 3. So the answer is 3!!
