Answer:
Pat has lost 12 teeth.
I got a calculator and divided 32 by 8, then timed that answer (4) by 3.
32 ÷ 8 = 4
4 x 3 = 12
If the question had asked how many teeth Pat has, the answer would be 20, but that isn't correct for this question. It asks how many teeth she has lost, and that would be 12.
hope this helps
