Answer:
[tex]1\frac{1}{6}[/tex]
Step-by-step explanation:
so first find the common denominator which is 162
so on 4/9 multiply 18 to denominater and numerator which makes it 72/162
next multiply 9 to numerator and denominator in 13/18 which makes it 117/162
so now add:
[tex]\frac{72}{162} +\frac{117}{162} = \frac{189}{162}[/tex]
so now simplification.
189/162 can be reduced by 3
63/54 is our new answer. now we can reduce it by 9
7/6 is our new answer. now we must change it to a mixed number which is [tex]1\frac{1}{6}[/tex]
hope this helped!
