Question

Fill in the blanks:

$\frac{12}{18}=\frac{\square }{15}$

Answer 1

We have, $\frac{12}{18}=\frac{\square }{15}$

Let us fill the blank with $x$.

$\frac{12}{18}=\frac{x}{15}$

After cross multiplication, we get

$\begin{array}{rcl}x\times 18& =& 12\times 15\\ 18x& =& 180\\ x& =& \frac{180}{18}\\ x& =& 10\end{array}$

Hence, the answer is $10$.
