Answer:

[tex]\frac{95}{14}[/tex]

Step-by-step explanation:

[tex]4\frac{1}{2} = \frac{9}{2}[/tex]
[tex]2\frac{2}{7} = \frac{16}{7}[/tex]
Re-write expression with new fractions: [tex]\frac{9}{2} + \frac{16}{7}[/tex]
Find a LCM for the two denominators: 2 and 7 share 14
Change the fractions, so they have a common denominator: 9/2 = 63/14, 16/7 = 32/14
Re-write expression with new fractions: [tex]\frac{63}{14} + \frac{32}{14}[/tex]
[tex]\frac{63}{14} + \frac{32}{14} = \frac{95}{14}[/tex]

I hope this helps!
