PHP math question -

-

Let's say I divide it by 100 times so that the percent is received 93.33333333333333 How can I show it using 93.3% php?

Here is the code. 

  $ percent = ($ average / 15) * 100;

The sprintf function is created for this (this See also)): 

  resonant sprinkle ('% .1f %%', $ percent);

Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from.
