Round 6.487 and 2.049 to the hundredths place.<br><br> What is the sum of the rounded numbers?
sergey [27]

Hello there! 6.487 rounded to the nearest hundredths place is 6.49 and 2.049 rounded to the hundredths place is 2.05. The sum of these numbers is 8.54.

Remember: If the number value after the value you are rounding is equal to or greater than 5, round up. If it is less than 5, round down.

With this in mind, let's round the numbers:

First: 6.487 rounded to the hundredths place would be 6.49, since 7 is greater than 5.

Second: 2.049 rounded to the hundredths place would be 2.05, since 9 is greater than 5.

Next, we will add the numbers together

2.05 + 6.49 = 8.54.

So, this is our final answer. I hope this answers your question & have a great day! :)

Which is bigger 0.96 0r 19/20
REY [17]
0.96 or 19/20

0.96 as fraction = 96/100 = 19.2 / 20      5 into 96 is 19.2 and 5 into 100 is 20

So 0.96 is the same as 19.2/20

Since 19.2 / 20  and 19 / 20 have the same denominator,  therefore the 19.2 / 20 is bigger than 19 / 20.

So the 0.96 is bigger than the 19 / 20.
