Every odd number.
Multiplying two even numbers gives an even number.
Multiplying an odd and an even number gives an even number.
Multiplying two odd numbers gives an odd number.

How about: 5*84 = 420 as one example
5+5+5+5+1 That is only 5 numbers being added. There can be no answer for six numbers for the following reasons: The numbers are all odd. Two odd numbers make an even number. Two even numbers make an even number. 21 is odd. Take 6 odd numbers and add them up in pairs. Each pair of odd numbers gives an even number so there are 3 even numbers. Even + Even + Even = Even. So sum of any six odd numbers is even but 21 is not even.
35 & 49 The multiples of 5 between 30 & 50 which are odd are: 5 x 7 = 35 5 x 9 = 45 So for a ratio of 5 : 7, whatever the 5 is multiplied by the 7 must also be multiplied by: 7 x 7 = 49 7 x 9 = 63 63 is greater than 50, so multiplying 5 and 7 by 7 gives the solution of 35 & 49: 35 : 49 is the same ratio as 5 : 7
Odd numbers have a special property that when multiplied by any odd number, the product will always be odd. (The only exceptions are for different bases and modulus.) Examples include 3*5=15 35*3=105 127*325=41275
49*5
35
3 x 5 x 5 = 75
two numbers multiplied together that gives you 20 are 10 and 2. also have 5*4, 1*20, 2.5*8 ect
How about: 5*84 = 420 as one example

The numbers are 3, 5, 7, 9, 11, 13, 15 and 17.
