Question

George has managed to get 3 submarine sandwiches for his birthday party. If each of his friends will eat $\frac{1}{5}$th of a sandwich, how many friends can George invite?

• A. 5
• B. 15
• C. 12
• D. 1

Answer 1

The correct option is B 15

Each of George's friends consumes $\frac{1}{5}$th of a sandwich.

$\text{Number of friends George can invite}=\frac{\text{Total number of sandwiches}}{\text{Sandwich consumed by each sandwich}}$

$=3÷\frac{1}{5}$

$=3\times \frac{5}{1}$

$=15$

George can invite 15 friends.
