The sum of 15 non-zero natural numbers is 76, and one of them must be greater than or equal to 6. Why?
If they are all less than 6, that is to say, at most 5
that
15×5=75＜76
It contradicts the meaning of the title
If a and B are both non-zero natural numbers and two-thirds of a is equal to three-quarters of B, what is the simplest integer ratio of a and B? What is the ratio?
Two thirds a equals three quarters B
8a=9b
a:b=9:8
The ratio is 9 / 8
Are natural numbers integers greater than 0 and equal to 0
A set of natural numbers is a set of nonnegative integers
