Question

mr. adagio counted 30 students at last week’s art club meeting. this week, there are also drama auditions, so he expects 60% fewer students to attend. mr. adagio wants to know how many students to expect at this week’s art club meeting. this week’s attendance = last week’s attendance − 60% of last week’s attendance how can you find the expected decrease in attendance? last week’s attendance: 30 students 60% of last week’s attendance = ? ? 30 this week’s attendance: ? expected decrease: 60% of 30 students

Explanation:

Step1: Convert percentage to decimal

To find 60% of a number, we first convert 60% to its decimal form. 60% is equivalent to $0.6$ (since percent means "per hundred", so 60% = $\frac{60}{100} = 0.6$).

Step2: Multiply by last week's attendance

Now, we multiply this decimal by last week's attendance (30 students). So the formula for 60% of last week's attendance is $0.6 \times 30$. Calculating this, $0.6 \times 30 = 18$. This is the expected decrease. Then, to find this week's attendance, we subtract this decrease from last week's attendance: $30 - 18 = 12$. But for the "60% of last week's attendance" part, the first box should be $0.6$ (or $\frac{60}{100}$ which is 0.6) and the second box is "×" (multiplication).

Answer:

For the first dropdown (the number part): $0.6$ (or 60% as a decimal, which is 0.6)
For the second dropdown (the operation): $\times$ (multiplication)
And the expected decrease is 18 students, so this week's attendance is $30 - 18 = 12$ students. But focusing on the "60% of last week's attendance" calculation, the two boxes are filled with $0.6$ and $\times$ respectively.
