12(4+5)


12(8+5)


6(6+10)


6(8+12)

Answer 1

If
48+60= 108
Now checking the options:
A. 12(4+5)= 48+60=108
B. 12(8+5)= 96+60=156
C.6(6+10)= 36+60=96
D. 6(8+12)= 48+72=120
Therefore option A is correct.

Answer 2

The answer is:

⇨ A

Work/explanation:

Let's find something that 48 and 60 have in common.

In other words, we find their GCF (greatest common factor).

The GCF of 48 and 60 is 12.

So I factor it out :

12(4 + 5)

which is A.

Hence, A is the right answer.
