If p is an even integer and q is an odd integer, which of the following must be an odd integer? 选项: A、 $$\frac{p}{q}$$ B、 pq C、 2p+q D、 2(p+q) E、 $$\frac{3p}{q}$$ 答案: C
正确答案:A解析:The correct answer is A. To answer this question, note that odd numbers are every other number: 1, 3, 5, 7, ... , etc. So an odd number plus or minus 2 would create another odd number. Therefore, 7y+7 would be the next smaller odd integer. Factor out a 7 to...
The sum of an odd number and an even number can be expressed as (2n+1)+(2m), where n and m are integers. (2n+1 must be odd, and 2m must be even.) Their sum is equal to 2n+2m+1, or 2(m +n)+ 1. Since (m+ n) is an integer, the quantity 2(m +n)+1must represen...
