Final answer:
There are 120 tenths in 12 wholes, as each whole consists of 10 tenths, and multiplying 12 by 10 gives us 120.
Step-by-step explanation:
The question asked is how many tenths are in 12 wholes. To find the answer, we consider that one whole consists of 10 tenths. Therefore, to find the total tenths in 12 wholes, we would multiply 12 (the number of wholes) by 10 (the number of tenths in one whole).
12 wholes × 10 tenths/whole = 120 tenths.
So the correct answer to the question is 120 tenths, which corresponds with option C.
