Question

The sum of a few numbers if 30, the first number is 2 less than the second, and the third is 4 less than the first. What are the order of numbers and what are the numbers?

This is a post by one of my classmates that I'm supposed to solve. I'm probably doing it wrong, but I can't seem to get 30 with the equations he's giving me. I'm either getting 31 or 28... please help?

Answer 1

You can get really close by doing 10.999999999+11.999999999+6.999999999 but you'll never quite get to 30 because it's a limit
