Which of these numbers have their last digit in the tenth place: 0.02, 0.2, 0.14, or 0.3?

Let’s think about place value. To the left of the decimal place is the ones place, or the units place. To the right of the decimal place, we have tenths, hundredths, thousandths. Our question is asking which of these have their last digit in the tenths place, here. Let’s see.

0.02 is two hundredths. Its last digit is in the hundredths place. Two hundredths does not qualify. How about 0.2? That’s two tenths. And the last digit does fall in the tenths place. That works. 0.14, 14 hundredths, the last digit here falls in the hundredths place. It doesn’t qualify. We can check the last number we were given. Three tenths, 0.3, the last digit falls in the tenths place here. To answer the question which of these numbers have their last digit in the tenths place, two tenths and three tenths.
