what is blan divide 2 equals 34

Lets say blank is a letter, blank is the letter b okay?

b/2=34

so blank is twice as much as 34 because 34 is half of blank.

because blank is twice as much as 34 you would multiply 34 by 2 to find blank.

$${\mathtt{34}}{\mathtt{\,\times\,}}{\mathtt{2}} = {\mathtt{68}}$$

68=blank

ask me if you have any questions!
