Final answer:
The number formed by 15 ones, 13 tenths, 16 hundredths, and 81 thousandths is 16.441 when combined according to their place values.
Step-by-step explanation:
The question asks to combine different place values into a single number. We have 15 ones, 13 tenths, 16 hundredths, and 81 thousandths. To write this as a number, we place each value in its correct position according to place value in our number system. Therefore, the number is composed as follows:
- 15 ones => 15
- 13 tenths => .1
- 16 hundredths => .06 (since the tenths place is already occupied by the 1 from 13 tenths, we place the 6 in the hundredths place)
- 81 thousandths => .081 (this will add to the hundredths and tenths place)
Combining these we get 15 + 1.3 + 0.06 + 0.081 = 16.441. So the answer to the question is 16.441.
