#### Explanation:

We can express the ratio as an equation in $\textcolor{b l u e}{\text{fractional form}}$

$\Rightarrow \frac{9}{3060} = \frac{8}{x}$

where x represents the amount her son received.

$\textcolor{b l u e}{\text{cross-multiply}}$

$\Rightarrow 9 x = 8 \times 3060$

$\Rightarrow x = \frac{8 \times 3060}{9}$

$\textcolor{w h i t e}{\Rightarrow x} = 2720$

Total given to children =3060+2720=$5780 Mar 16, 2017 $5780

#### Explanation:

There are several ways of approaching this.

The monies are split into 8 parts for the son and 9 parts for the daughter. This makes a whole of:

$8 + 9 = 17 \text{ parts}$

Let the whole sum be $x$

Then we have for the daughter -> 9/17x=$3060 Multiply both sides by $\frac{17}{9}$[17/9xx9/17]xx x=17/9xx$3060

1xx x =\$5780
