What values are the equivalent of a whole note (in common/simple time we'll get to compound time a bit later

A whole note is the correct answer.

Explanation:

When we talk about musical concepts, the term whole note refers to the one that has the longest time value, which in this case is equivalent to four beats (4/4 time.) It is also called "a semibreve." So, in other words, the equivalence of a whole note is the same as two half notes and four quarter notes, and so on.

sorry to hear, it's probably frustrating sometimes
