Answer:
Let's denote Kendra's number as \(K\). According to the information given:
1. Kendra's number (\(K\)) is 1 less than Alex's number.
\[K = 27 - 1 = 26\]
2. Devon's number is 10 more than Kendra's number.
\[Devon = K + 10 = 26 + 10 = 36\]
So, Kendra's number is 26, Alex's number is 27, and Devon's number is 36.
