Find the value of: 1 / 4(2/7) + 1 / 3(11/13) + 1 / (5/9)

Solution:

On converting mixed fractions to improper fractions and on further solving we get,

= 1/(30/7) + 1/(50/13) + 1/(5/9)

= 7/30 + 13/50 + 9/5

= 35/150 + 39/150 + 270/150 = 172/75.

Therefore the value of 1 / 4(2/7) + 1 / 3(11/13) + 1 / (5/9) is 172/75.
