how many groups of 12 go into 42

Answer 1

To find out how many groups of 12 go into 42, you can divide 42 by 12:

\[ \frac{42}{12} = 3.5 \]

This means there are 3 full groups of 12 in 42, with a remainder (or additional half group) left over. Thus, 3 groups of 12 fit into 42, and there is some leftover (6) that does not complete another full group of 12.
