Given the statement:
⅓ of a number less than 9 is equal to 7
Representation:
The numerical statement can be written as,
⅓x - 9 = 7
where x is equal to the number.
Solution:
In order to find for the missing number, the first step is to transpose -9 on the other side of the equation, hence we must take note that in transposing a number, the sign changes.
⅓x - 9 = 7
⅓x = 9 + 7
⅓x = 16
Multiply both sides by 3 in order to cancel out ⅓x.
x = 48
Final answer:
x = 48
