Answer:
Step-by-step explanation:
1/3+1/5×1/9 = 1/3+1/45 = 9/45+1/45 = 10/45 = 2/9
use multiplication first, multiply 1/5 and 1/9 to get 1/45
then add 1/3,
(multiply 1/3 by 15/15 to get 15/45)
add 15/45 and 1/45 to get 16/45
then add 1/3,
(multiply 1/3 by 15/15 to get 15/45)
add 15/45 and 1/45 to get 16/45
