15 is 125% of 12.

When translating a question from English to "math", it is useful to know what some key English words mean in math:

- "is" means
#=# - "percent" means
#xx 1/100# - "of" means
#xx#

With these key phrases in mind, it is not hard to translate the question:

#color(grey)"15 is what percent of 12"#

#15=" "x xx 1/100" "xx 12#

Having translated the question into math, we can simplify and solve for

#" "15" "=(12x)/100#

#(""^5cancel(15) * 100)/(""^4cancel(12)) = x#

#(5 * cancel(100)^25)/(cancel(4)^1) = x#

#" "5 * 25" "= x" "=125#

So 15 is 125% of 12.
