Answer:
13/50
Explanation:
We already have our first value 13 and the second value 26. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple formula below:
13 = 26% x Y
13 = 26/100 x Y
Y = 13 x 100/26
Y = 13 x 100 / 26
y = 50
