If s represents a number, then which of these means the same as the expression s × 7?
A. Seven divided by a number
B. Seven times a number
C. Seven less than a number
D. Seven more than a number
Answer (2)
The expression s × 7 means 's' multiplied by 7.
Evaluate each option to determine which one matches the expression.
Option B, 'Seven times a number', is equivalent to s × 7.
The correct answer is B.
Explanation
Understanding the Problem The problem states that 's' represents a number and asks us to identify which of the given options is equivalent to the expression s × 7.
Interpreting the Expression The expression s × 7 means 's' multiplied by 7, which is the same as 7 multiplied by 's'. In simpler terms, it means seven times the number 's'.
Evaluating the Options Now, let's examine the options:
A: Seven divided by a number (7 / s) - This is not the same as s × 7.
B: Seven times a number (7 × s) - This is the same as s × 7.
C: Seven less than a number (s - 7) - This is not the same as s × 7.
D: Seven more than a number (s + 7) - This is not the same as s × 7.
Identifying the Correct Option Therefore, the correct answer is option B, which states 'Seven times a number'.
Examples
In real life, if you are buying 7 items that each cost the same amount 's', the total cost would be represented by s × 7, which means seven times the cost of one item. For example, if one candy bar costs $2, then buying 7 candy bars would cost 7 × $2 = $14.
The expression s × 7 means 's' multiplied by 7. Among the options given, only option B, which states 'Seven times a number', is equivalent to s × 7 . Thus, the correct answer is option B.
