Answer:
18 Times
Step-by-step explanation:
Multiply the least amount by the six weeks. You multiply the least amount because the frog came every 3 days and the raccoon came every 7 days. Piper would see the frog and the raccoon at the same times on the least of the frog. The raccoon came all week while the frog came on limited times.
Hope this helps,
