12:9, 12/9, and 12 to 9. The way I got 12 and 9 was by simplifying 60/45.
C. 4
14 + 13 - (23)
27 - 23

Hi,
AxB = 0 means A=0. or B=0
so 2 solutions :
4x-3= 0
4x=3
x = 3/4
and x+2 = 0.
x= -2
solutions are : -2 +and 3/4
Add 70+93, then divide by the number of numbers, which is 2.
70+90=163
163/2=81.5
Hope this helps!
