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

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.
