Answer:
add 12 and a number : 12 + c
Subtract a number from 12 : 12 - c
Divide a number by 12: c over 12
Multiply 12 by a number: 12c
Explanation:
Add 12 and a number:
Let c = any number then the statement "add 12 and a number" will be: 12 + c
Similarly,
As a number has to be subtracted from 12. Subtracting a number from 12 will be: 12 -c
The number has to be divided by 12 so the number will be the numerator and 12 will be the denominator.
Multiplication simply means 12*c OR 12c
