I don't think we will need to use a variable expression for this one.

3 weeks have 7 days, we know that.

So, the numerical expression would be 3 x 7 = 21

3: weeks
7: days
21: days in 3 weeks.

Hope this helped

since there are 7 days in one week
so 3 weeks = 3 X 7 = 21 days
so, 21 is the answer.
