Question

translate this phrase into a mathematical expression:
15 divided by 3 first, and 21 added to that total
after you pick your answer press go.
a b c d e
\\(\frac{15}{21}+3\\)

Explanation:

Step1: Analyze the first operation

The phrase says "15 divided by 3 first", so we translate that into a mathematical expression. The division of 15 by 3 is written as $\frac{15}{3}$.

Step2: Analyze the second operation

Then it says "21 added to that total". "That total" refers to the result of $\frac{15}{3}$, so we add 21 to $\frac{15}{3}$. The expression becomes $\frac{15}{3}+21$.

(Note: The given option $\frac{15}{21}+3$ is incorrect. The correct expression based on the phrase is $\frac{15}{3}+21$)

Answer:

The correct mathematical expression is $\frac{15}{3}+21$ (the provided option in the image is incorrect; the correct one is derived from the phrase as above).
