Write three tens and five tenths as
a decimal.
First, we can make a place value
chart. Starting all the way on the left
and moving to the right, we have hundreds, tens, ones, the decimal then tenths,
hundredths, thousandths. We have three tens — so we write a
three in the tens place — and five tenths. We add a five to the tenths
place.
How do we finish this problem? First, we bring down the decimal
place and then we add a zero as a placeholder. Three tens is the same thing as
30.
Three tens and five tenths is equal
to 30 and five tenths. We write that 30.5.
