Make the numerators to be the same since they are equal.
3/4 A= 4/5C
12/16A= 12/15C
Total people-> 16u+15u= 31u
a) 15/31 (ans)
b) Using grouping,
In 1 group, there are 16 adults and 15 children. So the difference of meatballs in 1 group-> 16 x 4 - 15 x 2= 34
No. Of groups to have a total difference of 850
-> 850 รท 34= 25
25 x (16+15)= 775 (ans)
