Greetings!
"What is 4/9+1/3 in fraction from?"...
When adding or subtracting rationals, we must find the LCM (The Lowest Common Denominator.)
This can be done by listing the multiples of the denominators:
9: 9,18
3: 3,6,9,12
9*1=9
3*3=9
The LCM is 9.
We must do the same operation to the numerators:
4*1=9
1*3=3
The new fractions would be:
4/9+3/9
4+3=7
7/9
The answer would be 7/9.
Hope this helps.
