2 ones, 48 tenths and 5 hundreds =
506.8
2.485
To simplify and calculate the sum of 2 ones, 48 tenths, and 5 hundreds, we need to convert all the numbers to the same unit. Let's convert everything to the decimal form.
Since there are 2 ones, we can write it as 2.0 (because there are no tenths or hundredths).
For 48 tenths, we can write it as 4.8 (as there are 4 whole numbers and 8 tenths).
For 5 hundreds, we can write it as 500.0 (since there are 5 whole numbers and no tenths or hundredths).
Now we can add them together:
2.0 + 4.8 + 500.0 = 506.8
Therefore, the sum of 2 ones, 48 tenths, and 5 hundreds is 506.8.
