To solve this problem, we need to divide 72 by 6 to find out how many are in each group, and then subtract 4 from that result.
Let's break it down step by step:
1. Divide 72 by 6 to find out how many are in each group:
\[ \frac{72}{6} = 12 \]
2. Subtract 4 from that result to find out how many are in each group after taking four away:
\[ 12 - 4 = 8 \]
So, each group would have 8 items after taking four away from 72 and then dividing into 6 equal groups.
