Answer 2

To solve these equations, you can use cross-multiplication. Here's how you can do it:

1. $\frac{7}{28} = \frac{x}{12}$

Cross-multiply: $7 \times 12 = 28 \times x$

Simplify: $84 = 28x$

Divide by 28: $x = 3$

So, the solution is $x = 3$.

2. $\frac{14}{10} = \frac{21}{x}$

Cross-multiply: $14 \times x = 10 \times 21$

Simplify: $14x = 210$

Divide by 14: $x = 15$

So, the solution is $x = 15$.

3. $\frac{45}{25} = \frac{18}{x}$

Cross-multiply: $45 \times x = 25 \times 18$

Simplify: $45x = 450$

Divide by 45: $x = 10$

So, the solution is $x = 10$.
