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

What is the sign of c÷d when c &gt;0 and d &lt; 0.<br><br><br> Plzzz helppp im in class right now
kolezko [41]

Answer:

Negative

Step-by-step explanation:

Assume that you mean if c÷d is positive or negative when c > 0 and d < 0

c > 0 means that c is positive

d < 0 means that d is negative

positive divides negative is always negative.

Thus, c÷d is negative when c > 0 and d < 0
