3 ones, 4tenths, 5 hundredths and 2 tens = ?
23.45
To add these numbers together, let's start by placing them in order from highest to lowest value:
2 tens, 3 ones, 4 tenths, and 5 hundredths.
Next, let's convert them all to the same unit. Since the unit here is ones, we need to convert the tenths and hundredths to ones.
4 tenths can be written as 0.4 ones, and 5 hundredths can be written as 0.05 ones.
Now we can add them together:
2 tens + 3 ones + 0.4 ones + 0.05 ones
To convert 2 tens to ones, we multiply it by 10:
2 tens = 2 × 10 = 20 ones
Now we can add them all together:
20 ones + 3 ones + 0.4 ones + 0.05 ones
= 23.45 ones
Therefore, 2 tens, 3 ones, 4 tenths, and 5 hundredths is equal to 23.45.
