9:14 is equivalent to 9/23.
We can set up the following proportion:
9/23=a/7.
Now, we just solve for a by the Cross Product Property.
9(7)=23(a)
Now, just divide by 23 on both sides to isolate “a.”
63/23=23a/23
After simplifying, a=2.739.
Therefore, 9/23=2.739/7
When reduced into decimal form, .391=.391, so we know the proportion is indeed correct.
