A toy company manufactures miniature cars. They sell miniature sports cars in a box. They sell 12 miniature trucks in a box. Mrs. Murphy wants to buy an equal number of sports cars and trucks for the Boys and Girls Club. What is the least number of miniature sports cars she can buy? I need help.

Question

There is too much words.

Answer 1

The least number of miniature sports cars she can buy is 60 cars which is 5 boxes.

Answer 2

It would help if you proofread your questions before you posted them.

How many miniature sports cars are in a box? Angela is assuming there are 12 in a box, which would mean that Mrs. Murphy would only need to buy one box of each.

Answer 3

Sorry I mean, A toy company manufactures miniature cars. They sell 12 miniature cars in a box. They sell 10 miniature trucks in a box. Mrs. Murphy wants to buy an equal number of sports cars and trucks for the Boys and Girls Club. What is the least number of miniature sports cars she can buy?

I don't know how I messed that up. I really just need for someone to explain the process. My teacher gave us the answer which is 60. Angela is right. But I need someone to explain how my teacher got the answer.

Answer 4

LCM(10,12) = 60

All multiples of 10 end in 0
What's the first multiple of 12 that ends in 0? Well, 2*5 = 10, so 5*12 = 60

Or, using the factors,
10 = 2*5
12 = 2^2 * 3^1
The LCM must contain the highest power of each prime divisor
In this case, that's 2^2 * 3 * 5 = 60
