How many different ways can you write a fraction that has a numerator of 2 as sum of fraction

Let's say we have the fraction 2/9.

We can split this one fraction into two by modifying the numerator, like so: 2/9 = 1/9 + 1/9

This works because since both fractions have a numerator of 9, you can easily add the numerators to give 2, and that will give 2/9 in return. However, you can't separate the denominators.

2/9 is NOT equal to 2/6 + 2/3

2/9 = 1/9 + 1/9

2/9 = 0.5/9 + 1.5/9 (which simplifies to 1/18 + 3/18, also giving 2/9)

2/9 = 0.5/9 + 0.5/9 + 0.5/9 + 0.5/9 = 1/18 + 1/18 + 1/18 + 1/18

I basically split it up into more and more fractions that add up to give 2/9. So, in short, there are infinitely many ways to do it.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
