While attending a school carnival, you estimate the ratio of children to adults as If there are 180 people at the carnival, abou

Karolina [17]

Answer:

180-n_c

Step-by-step explanation:

Given that the ratio of children to adults is 2:1.

Let $n_c$ and $n_a$ be the number of children and adults in the school carnival.

So, $\frac {n_c}{n_a} = \frac 2 1$

$\Rightarrow n_c = 2 n_a \cdots(i)$

Given that the total number of peoples in the carnival =180

So, $n_c + n_a = 180$

$\Rightarrow n_a = 180-n_c \cdots(ii)$

Now, from equations (i) and (ii), we have

$n_c = 2(180-n_c) \\\\\Rightarrow n_c = 360 -2 n_c \\\\\Rightarrow n_c +2n_c = 360 \\\\\Rightarrow 3 n_c = 360 \\\\\Rightarrow n_c = 360/3 = 120.$

Hence, the number of children in attendance is 120.
