Answer: The answer is 6 tenths
Step-by-step explanation: You may all know that 45 thousandths is written like this: 0.045 and 6 tenths is written like this: 0.6. It would make perfect sense because there is no number in the tenths place in 45 thousandths and it goes from thousandths, hundredths, tenths and ones. The thousandths being the least and the ones being the most. That means if there is no number in the tenths place in 45 thousandths and there is 6 in 6 tenths, that means that 6 tenths is greater.
