Yay! All are correct.
Your reasoning is correct. To find the approximate number of hours Yolanda plays soccer in a year, you need to multiply her monthly playing time (8 2/3 hours) by the number of months in a year (12).
To multiply a whole number with a fraction, you can convert the whole number into a fraction by writing it over 1. So, 12 can be written as 12/1.
Next, multiply the numerators (8 and 12) together to get 96, and multiply the denominators (3 and 1) together to get 3. This gives you 96/3.
Now, you can simplify the fraction by dividing the numerator (96) by the denominator (3). 96 รท 3 equals 32.
Therefore, Yolanda plays approximately 32 hours of soccer in a year.
Since none of the given answer choices match 32, it seems there might be a calculation error. Let's review the options again:
A. 416
B. 104
