3 * (½ + ⅓ ) =

Rationale

3 * (½ + ⅓) = 3 * (5/6) = 15/6 = 2.5 or 2 1/2.

To solve the expression, we first need to add the fractions ½ and ⅓. The least common denominator is 6, converting the fractions to 3/6 and 2/6 respectively, which sums to 5/6. Multiplying by 3 gives us 15/6, simplifying to 2.5 or 2 1/2, which is equivalent to 2 65 in mixed number form.

A (221) CORRECT

This option is a whole number that does not result from the calculation of the given expression. The correct multiplication and addition of fractions lead to a value of 2.5, which is far less than 221.

B (2 65) YOUR ANSWER

This option looks like a mixed number but is incorrectly formatted. The correct result of the calculation is indeed 2 1/2, which is expressed as 2 65 in improper fraction form. Thus, while it may represent a similar value, it is not accurately presented.

C (361) YOUR ANSWER

This choice is also a whole number, which does not correspond to the outcome of the calculation. The result of the expression is significantly lower than 361, making this an incorrect option.

D (365) YOUR ANSWER

Similar to the previous options, 365 is a whole number that is not derived from the calculation provided. The operations involved do not yield a value close to 365, thus making this choice incorrect.

Conclusion

The correct answer to the expression 3 * (½ + ⅓) evaluates to 2 1/2, which can also be expressed as 2 65 when formatted correctly. All other options provided are either incorrect whole numbers or misrepresented forms of the correct answer. Understanding how to perform the calculations accurately is essential for reaching the right conclusion.

3 * (½ + ⅓ ) =

3 * (½ + ⅓) = 3 * (5/6) = 15/6 = 2.5 or 2 1/2.
