1) a daycare center expects 20 babies on a given day. how many staff should the center have work that day to maintain a 1/4 ratio?
Answer
Explanation:
Step1: Set up proportion
Let $x$ be the number of staff. The ratio of staff to babies is $\frac{x}{20}$, and we want this ratio to be $\frac{1}{4}$. So we set up the proportion $\frac{x}{20}=\frac{1}{4}$.
Step2: Cross - multiply
Cross - multiplying gives us $4x = 20\times1$.
Step3: Solve for $x$
Dividing both sides of the equation $4x = 20$ by 4, we get $x=\frac{20}{4}=5$.
