Jose says one third

Question

of the months in a year end in the letters​ "er." Mariana says four twelfths
of the months in a year end in the letters​ "er." Who is​ correct? Explain.

Answer 1

Mariana is correct.

There are 12 months in a year, and four of them end in the letters "er": September, October, November, and December.

On the other hand, Jose is incorrect. One third of 12 is 4, but there are actually four months that end in "er," not three.
