i don't know about the formula too...
but this is how i do this type of questions..
85% ----> 13
100% ----> (100/85) x 13
= 15.29 (4s.f.)
you can also do it this way...
85% means it is 85 portions out of 100 portions
since 85 portions is equal to 13
then 1 portion is 13/85
which is 0.1529
then 100 portions will be 0.1529 x 100
which is 15.29 also...

13/x = 85/100 cross multiply and divide
Lnki has the format kind of backwards, although she multiplied and divided correctly
It's 13 is to x as 85 is to 100

First convert 85% to decimal. Remove the percent sign
85/100 = 0.85
Divide 13 by the decimal
13 ÷ 0.85 = 15.29411765
The answer is 15.29 Rounded to two decimal places.
