Question : What is the value of $\frac{5}{11}$ of $\frac{3}{7}+\frac{7}{11} \times \frac{55}{21}-\frac{8}{22} \div \frac{16}{33}$?
Option 1: $\frac{1088}{927}$
Option 2: $\frac{1027}{924}$
Option 3: $\frac{1811}{956}$
Option 4: $\frac{1029}{945}$
Correct Answer: $\frac{1027}{924}$
Solution : $\frac{5}{11}$ of $\frac{3}{7}+\frac{7}{11} \times \frac{55}{21}-\frac{8}{22} \div \frac{16}{33}$ $=(\frac{5}{11}\times\frac{3}{7})+\frac{7}{11} \times \frac{55}{21}-\frac{8}{22} \div \frac{16}{33}$ $=\frac{15}{77}+\frac{7}{11} \times \frac{55}{21}-\frac{8}{22} \times \frac{33}{16}$ $=\frac{15}{77}+\frac{5}{3}-\frac{3}{4}$ $=\frac{180+1540-693}{924}$ $=\frac{1720-693}{924}$ $=\frac{1027}{924}$ Hence, the correct answer is $\frac{1027}{924}$.
Question : Instead of dividing 391 cookies among 3 children A, B, C in the ratio $\frac{1}{5}:\frac{1}{4}:\frac{1}{8}$, it was divided into the ratio $5:4:8$. Who gains most and how many?
Option 1: A, 21 cookies
Option 2: B, 78 cookies
Option 3: C, 99 cookies
Option 4: C, 78 cookies
Correct Answer: C, 99 cookies
Solution : Case 1: A : B : C = $\frac{1}{5}:\frac{1}{4}:\frac{1}{8}$ LCM of 5, 4, and 8 is 40. So, A : B : C = $\frac{1}{5}×40:\frac{1}{4}×40:\frac{1}{8}×40$ = 8 : 10 : 5 Sum of A + B + C = 8 + 10 +
