A proportion is a pair of equal ratios.
Hello,
8+h>2+3h
==>-2h>2-8
==>-2h>-6
==>h<3
Answer C
the answer will be 20 times 3 that is 60
k, n - integers
2k+1 - an odd integer
2n+1 - another odd integer
The product of them:
(2k + 1)(2n + 1) =
= 4kn + 2k + 2n + 1 =
= 2(2kn + k + n) + 1
The product of integers (2kn) is integer
and the sum of them (2kn+k+n) also is integer
So (2k + 1)(2n + 1) = 2(2kn + k + n) + 1 is an odd integer
