Answer:
10.5; 13.5
Step-by-step explanation:
7:8:9=_:12:_
8 is corresponding to 12
12/8=1.5
8*1.5=12
So, multiply 7 & 9 by the same value (1.5) to get the answer.
7*1.5=10.5 or 10 1/2
9*1.5=13.5 or 13 1/2
The ratios are:
7:8:9=10.5:12:13.5
The blank spaces are 10.5 and 13.5 respectively.
Hope this helps ;)
