The answer is (a)..........
From the amounts that are given, the ratio of the earnings will be 3:2:1.
<h3>How to calculate ratio</h3>
From the information, the eldest earns R270, the middle child earns R180 and the youngest earns R90.
Therefore, the common factor to the numbers will be 90. Therefore, the ratio will be:
270/90 = 3
180/90 = 2
90/90 = 1
The ratio is 3:2:1.

<em>zero product property (Angela)</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em> (Angela)</em>
<em>3x² + 10x = 0</em>
<em>x(3x + 10) = 0</em>
<em>x = 0 => x₁ = 0</em>
<em>3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3</em>
<em>Good luck !</em>
Inequalities will have a <, >, <=, =>, = or will be worded as "Less than", "greater than", etc.
Equations must have mathematical functions and equal sign.
15=3x is an equation since 3x = 3*x
Finally, expressions are mathematical functions that have no equal signs.
As the opposite sides of rhombus are parallel. Also, the opposite sides of rhombus are equal. also it satisfies all other properties of a parallelogram.
Hence , as opposite sides of rhombus are parallel and equal also .
So
A rhombus is ALWAYS a parallelogram.
