• False

• True

• I don't know

12 tenths + 9 tenths = ________ tenths = ________ one(s) ________ tenths

• 21 tenths = 0 ones 21 tenths

• 21 tenths = 20 ones 1 tenths

• 20 tenths = 2 ones 0 tenths

• 21 tenths = 2 ones 1 tenths

5 tenths - 2 tenths = ________ tenths = ________

• 7 tenths = 0.7

• 3 tenths = 0.03

• 3 tenths = 0.3

• 3 tenths = 3

57.03 + 2.08 = ?

• 59.11

• 59.83

• 77.83

• 60.1

60.91 - 2.856 =

• 56.245

• 3.235

• 32.35

• 58.054
