Adding fractions with the same numerator

[@FaerieDragonZook]

If the numerator is the same, it actually does help (slightly). You can *add* the denominators together, then multiply it by the shared numerator to get the answer numerator. 5+7=12, then 12×2=24.

That’s a coincidence

[@adiaphoros6842]

@@luckygamer9197 No, it’s not a coincidence. They only gave an algorithm for the numerator of the result.
Proof:
k/a + k/b = (ka+kb)/(ab)
k/a + k/b = k(a+b)/(ab)
In this case:
k = 2
a = 5
b = 7
Getting the denominator of the result is easy enough, just multiply the denominators of the addends.

[@sandrachen3500]

5a+7a=12a. 5x2+7x2=12x2. It’s basically collecting like terms, but we know that a=2

[@mariodenis1111_edits]

Acctually, It does help. When two denominators are added up togother and the sum is equal to the numerators, You could just use multiplication if its easier
For example: 25/5 and 25/20, Multiplying it has the same result as adding. If d1 + d2 = numerator (d is denominator), The multiplication result is the same as addition.

[@Pacvalham]

a/b + a/b = 2a/b, not = a/b or (a + a) / (b + b)

[@Pacvalham]

n + n = 2n
If n = a/b, then a/b + a/b = 2a/b

I thought this was class 3 level maths?¿

This whole channel is class 3 level maths go to his main for discrete math

@@CameronSolanki Aight thanks mate

[@vyshnavanil9653]

Can you make like a video telling us different was to solve any random equations like squaring both sides etc if that made any sense. 🙂
Edit: i meant different ways to solve an equation kinda things

[@boston4635]

What

[@ale4462]

Sometimes (meaning really rare) squaring both sides would simplify things but most times it just makes it harder

The first answer is : 24/35,
the second answer is : 5/9.
