Question

1. this month, there were 15% fewer cloudy days than last month. the number of cloudy days this month is % of the number of cloudy days last month. 6. at the start of the day

Explanation:

Step1: Define last month's cloudy days

Let the number of cloudy days last month be \( x \).

Step2: Calculate this month's cloudy days

This month there are 15% fewer, so we subtract 15% of \( x \) from \( x \). 15% of \( x \) is \( 0.15x \), so this month's cloudy days are \( x - 0.15x = 0.85x \).

Step3: Find the percentage

To find what percentage this month's cloudy days (\( 0.85x \)) is of last month's (\( x \)), we calculate \( \frac{0.85x}{x} \times 100\% \). The \( x \) cancels out, giving \( 0.85 \times 100\% = 85\% \).

Answer:

85
