The clues translate to

n/d = 2/3
(n+2)/(d+2) = 3/4

Solving this by cross multiplying both:

3n = 2d
3(d+2) = 4(n+2) => 3d + 6 = 4n + 8

then substituting d = 3/2 n in the second:

9/2n - 4n = 2 => 1/2 n = 2 => n = 4

if n=4 then d = 3/2*4 = 6.

So the original fraction was 4/6

any help is appreciated :) here's the question: is the relationship between the side length of a square and the area of the squa
Bingel [31]
Area of a square = l x w

To find the area of a square you multiply the side length, and as we know the length and width of a square is the same, so the relationship between the side length and area is that the side length determines the area of a square.

An example is if the sides = 6

6 x 6 = 36

So the area would be 36

When you have the area of a square, you find the square root of the number to determine the side lengths

An example would be A = 49
The square root of 49 is 7 so, so the side length is 7.

Mariana [72]
I think probably not because everybody has a very different handspan and you probably wouldn't be able to get a very accurate average.
