拉维先生买了几盒巧克力。每盒装有12颗巧克力。拉维先生买的巧克力总数多于50颗但少于100颗。拉维先生吃了7颗，并把剩下的巧克力平均分给他的5个孩子。每个孩子分到了多少颗巧克力？ 答: ___

1. List the possible total number of chocolates based on the multiples of 12 between 50 and 100.

Multiples of $12$ between $50$ and $100$ are:
$12 \times 5 = 60$
$12 \times 6 = 72$
$12 \times 7 = 84$
$12 \times 8 = 96$

2. Determine which multiple leaves a remainder that is divisible by 5 after subtracting 7.

If total is $60$: $60 - 7 = 53$ (not divisible by $5$)
If total is $72$: $72 - 7 = 65$ (divisible by $5$)
If total is $84$: $84 - 7 = 77$ (not divisible by $5$)
If total is $96$: $96 - 7 = 89$ (not divisible by $5$)

So, the total number of chocolates is $72$.

3. Calculate the number of chocolates each child gets.

Number of chocolates for the children = $72 - 7 = 65$
Number of chocolates each child gets = $65 \div 5 = 13$
