She asked Rizza to keep 3 2 of them in the refrigerator. How many guavas did Rizza place in the refrigerator? How many apples did mother buy? Here are the 12 guavas.

How many small groups of guavas should be placed in the refrigerator? Two How many guavas are there in 2 small groups? 8 guavas So, 3 2 of 12 is 8. Rizza kept 8 guavas in the refrigerator. Let’s try to solve the problem in another way, by computation. 3 2 of 12 is the same as 3 2 x 12 = N. Solving this is easy because you already know how to multiply 2 fractions. 12 can be written as 1 12 in fraction form.
