MULTIPLICATION OF FRACTIONS BY WHOLE NUMBERS

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.
