The correct option is A Between 3.22 and 3.23

There are 2 tenths, 2 hundredths and 4 thousandths in the decimal number 3.224.
3.22 has 2 tenths and 2 hundredths, whereas 3.23 has 2 tenths and 3 hundredths.
2 tenths and 2 hundredths $<$ 2 tenths, 2 hundredths and 4 thousandths $<$ 2 tenths and 3 hundredths
