Answer:
6 groups
Explanation:
for this problem, we are figuring out how many partial numbers are in a whole number, so our first step would be to convert both sides to have the same denominator, meaning we will be using improper fractions
4 = 12/3
2 over 3 = 2/3
now that we have both numbers on common ground, we now just have to find how many times 2 will go into 12, so we divide
12 / 2 = 6
so 6 is the answer for this question, there are 6 groups of 2 over 3 (or 2/3) in 4
