Question

At a naming ceremony 5/9 of the people were adult men, 2/15 were adult women and the rest were children. If there were 28 children at the naming ceremony, find the total number of people at the naming ceremony.​

Answer 1

Answer:

$1 - ( \frac{5}{9} + \frac{2}{15} ) = 1 - ( \frac{25 + 6}{45} ) = \frac{14}{45 } \\ \frac{14}{45} = \frac{28}{x} \\ x = 90$
