Regrouping
What is one-hundredth more than 3.99?
- 19 hundredths + 1 hundredth = 10 hundredths, which is 1 tenth.

Common Mistakes to Watch For
Changing the wrong place
Wrong:One-tenth more than 5.27 is 5.28.
One-tenth changes the tenths digit: 5.27 + 0.1 = 5.37.
Not regrouping
Wrong:One-tenth more than 2.95 is 2.105.
9 tenths + 1 tenth = 10 tenths = 1 one: 2.95 + 0.1 = 3.05.
Helpful Math Tip
Think in money: one-tenth is a dime and one-hundredth is a penny. One dime more than $2.95 is $3.05.
