Tom bought 10 packages of miniature racing cars. Each package contains five cars. He gave each of his two nephews 1/5 of the cars. How many miniature racing cars are left with Tom?
Thoughts? Step-by-step reasoning:
User
Tom had 10 x 5 = 50 miniature racing cars. Tom gave 50 x 1 / 5 = 10 miniature racing cars to each of his two nephews. So, he gave a total of 10 x 2 = 20 cars to his two nephews. Therefore, Tom is left with 50 - 20 = 30 miniature racing cars.
Thus, the answer is 30.
