What past paper is this, can you please put a link to the question paper that this question came from :

Using proportions, considering the ratios, it is found that Danil receives 65.33 euros.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

Danil, gabriel and hadley share some money in the ratios 3:5:9. Hence, the fraction of the total amount that Danil and Hadley receive are given by:

$D = \frac{3}{17}n$

$H = \frac{9}{17}n$

The amount of money that hadley receives is 196 euros, hence the total amount is found as follows.

$196 = \frac{9}{17}n$

$n = \frac{196 \times 17}{9}$

n = 370.22.

Hence, the amount received by Danil is given by:

$D = \frac{3}{17}n = \frac{3}{17} \times 370.22 = 65.33$
