If n represents a number, write an expression for one-half of three less than the number.
number: n
3 less than n: n-3
half of that: (n-3)/2
No answer
The expression for one-half of three less than the number "n" can be written as:
(1/2) * (n - 3)
To write an expression for one-half of three less than a number represented by n, we can break it down into three steps:
Step 1: Representing "three less than the number"
To find "three less than the number," we subtract 3 from n. This can be written as n - 3.
Step 2: Finding "one-half" of the above expression
To find "one-half" of an expression, we multiply it by 1/2. Applying this to our expression from step 1, we have: (n - 3) * (1/2).
Step 3: Simplifying the expression
If needed, we can simplify the expression by distributing the (1/2) to both terms within the parentheses: (1/2) * n - (1/2) * 3. This simplifies to: (1/2) * n - 3/2.
Therefore, the expression for one-half of three less than the number n is (1/2) * n - 3/2.
