Given the sum 99=33+66, rewrite 33+66 using their GCF and multiplication.
__(1+2)
33+66 can be rewritten using their greatest common factor (GCF) and multiplication as follows:
33 + 66 = (1 * 33) + (2 * 33)
Now, we can factor out the GCF, which is 33, and rewrite the equation as:
33 + 66 = 33(1 + 2)
Therefore, 33+66 can be written as 33(1+2) using their GCF and multiplication.
