does anyone know 5/6+4/9=?

Question

anonymous · Answer

First you have to make the denominators the same. To do that, you multiply the numbers by different forms of 1, such as 5/5 or 3/3, which still leaves them equivalent.

anonymous · Answer

So do (5/6*3/3)+(4/9*2/2)

I got 1.27777777778 and I hope this helped:)

anonymous · Answer

which is 15/18+8/18=23/18
If you teacher is picky, then you can change it to a mixed number which is $$1\frac{ 7 }{ 18 }$$

The LCD is 18 not 40. 40 is not divisble by 6 nor 9.

anonymous · Answer

18?

♪chibiterasu · Answer

I don't even know where the 40 came from.

The "proper" way to find the lcd is to find the prime factors then only use the common factors once
6 :2 *3
9: 3*3
3 is common only use once. 
Lcd = 2*3*3 = 18
