Question

Fill in the blank : $\dots \dots \dots \dots \dots ..:108is1:2$

Answer 1

Given that, $\dots \dots \dots \dots \dots ..:108is1:2$

Let assume that the given blank as ' $y$ '

We get,

$y:108is1:2$

write ratios into fraction form and equate them,

$\frac{y}{108}=\frac{1}{2}$

on cross-multiplying, we get

$y\times 2=1\times 108$

transpose $2$to the RHS

$$\begin{gathered} y=\frac{1\times 108}{2} \\ y=\frac{108}{2} \\ y=54 \end{gathered}$$

Therefore, the value of $54:108is1:2$.

Hence, the answer for the given blank is $54$.
