Final answer:
To put the number 51.3 in a place value chart up to the thousandth place, identify the place values and add a zero as a placeholder in the hundredth place.
Step-by-step explanation:
To put the number 51.3 in a place value chart up to the thousandth place, we first identify the place values. For example, the digit 5 is in the tens place, 1 is in the ones place, and 3 is in the tenths place. Since we want to go up to the thousandth place, we need to add a zero as a placeholder in the hundredth place.
So, the number 51.3 in the place value chart up to the thousandth place would be:
5 tens + 1 ones + 0 tenths + 3 hundredths = 51.30
