Question

find an equivalent ratio where the total number of days is 100. hint: 28 is not a factor of 100, but 7 is a factor of 28. rainy days (part) 7 | total days (whole) 28 100

Explanation:

Step1: Set up proportion equation

Let $x$ = rainy days for 100 total days.
$$\frac{7}{28} = \frac{x}{100}$$

Step2: Simplify left-hand fraction

$$\frac{1}{4} = \frac{x}{100}$$

Step3: Solve for $x$

Multiply both sides by 100:
$$x = 100 \times \frac{1}{4}$$
$$x = 25$$

Answer:

25
