Answer:
A).
2/5 + 1/3
First find the LCM of the denominators
The LCM of 5 and 3 is 15
Add the fractions
We have
[tex] \frac{2}{5} + \frac{1}{3} = \frac{2(3) + 5}{15} \\ = \frac{6 + 5}{15} \\ = \frac{11}{15} [/tex]
B.)
5/9 - 1/2
Find the LCM of the denominators
LCM of 9 and two is 18
Next
Subtract the fractions
We have
[tex] \frac{5}{9} - \frac{1}{2} = \frac{5(2) - 9}{18} \\ = \frac{10 - 9}{18} \\ = \frac{1}{18} [/tex]
Hope this helps you
