Yes, It is.

Explanation:

QQ is the set of all numbers in the form QQ={a/b/a,b in ZZ; and b!=0}. As 1/2 is on this form, 1/2 is a rational number

By the other hand, RR is a superset containing QQ, it's say

QQsubRR, That means whichever element of QQ is also a element of RR and hence, 1/2 is also a real number
