Question

1. what is the missing number that makes the fractions equal?

\\(\frac{3}{4}=\frac{9}{x}\\)

Explanation:

Step1: Analyze fraction - equivalence

We know that $\frac{3}{12}=\frac{3\div3}{12\div3}=\frac{1}{4}$. Let the missing number be $x$, so we have $\frac{x}{9}=\frac{1}{4}$.

Step2: Cross - multiply

Cross - multiplying gives us $4x = 9\times1$.

Step3: Solve for $x$

Dividing both sides of the equation $4x=9$ by 4, we get $x=\frac{9}{4} = 2.25$.

Answer:

$2.25$
