Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2
___
Alternatively, you can simplify the given expression:

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
The forth picture is the one that represents 4.5
8 blocks because 2/10=1/5 so if they total 4/5 then 2/10+2/10+2/10+2/10=8/10=4/5
22/100:
You can actually divided the numerator and denominator by a number that can go into both 22 and 100 but also not get a remainder.
So 22/2= 11
And 100/2=50
Combined you get 11/50
