dear sir,
Hope u canhelp me .The number of adults at the zoo was 2/9 the number of children. there are 700 more children than adults. The number of men was four times the number of women. The number of girls was four times the number of boys. Find the total nymber of men and boys at the zoo.

I can get you started. When I read this problem I see the adults and children organized into small groups. Each group has 2 adults and 9 children. In each group the number of adults (2) is   ²/₉ the number of children (  ²/₉9 = 2).

In each group there are 7 more children than adults and hence there are 100 groups to give 700 more children than adults. Each group has 11 people in it so, in total, there are 1100 people at the zoo, 200 adults and 900 children.

Lets check my work so far.

200 adults and 900 children so there are 700 more children than adults.

  ²/₉900 = 200 so the number of adults is   ²/₉ the number of children.
