Answer:
253.520
Step-by-step explanation:
Let us see what is the thousandths place...
It is the third digit to the right.
253.5198 rounded is about
253.520.
I can tell because you take the thousandths place, look at the one to the right of it, then if it is greater than 5, you make the thousandths place greater. Since it's a 9, you move the extra 10 thousandths to the next thing- the hundredths. and you get 253.520.
Answer:
Her answer is not correct because the sum cannot be less than either addend.
The correct answer is
Step-by-step explanation:
Given:
The expression to add is given as:

Alaina got the answer as 
Let us first try to add the fractions and arrive at the answer.
Taking LCD of 18 and 20, we get LCD = 180
Now, making denominators of each fraction equal to 180 and changing the numerators accordingly.

Therefore, the result of Alaina is not correct because she got an answer which is less than the fraction
. But when we add two fractions, the result must be greater than either of the addend.
Therefore, her answer is not correct because the sum cannot be less than either addend.
