I think it's the second one on the top, because the dotted one is actually inside the bigger one and you can get a clear representation of the sizes.

Lee is thinking of two Numbers,the product is 18. the quotient is 2

defon

X, y - the numbers

The product is 18.
$xy=18$

The quotient is 2.
$\frac{x}{y}=2 \ \ \ |\times y \\
x=2y$

Substitute 2y for x in the 1st equation:
$2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)$

The numbers are 6 and 3 or -6 and -3.

When you add 18 to 1/4 of a number you get the number itself

JulijaS [17]

X - the number

$\frac{1}{4}x+18=x \\
18=x-\frac{1}{4}x \\
18=\frac{3}{4}x \ \ \ |\times \frac{4}{3} \\
18 \times \frac{4}{3} = x \\
6 \times 4=x \\
x=24$

The number is 24.
