How about: 5*84 = 420 as one example
The square of an odd number is always odd. This is because when you multiply an odd number by itself, the result retains the property of being odd. For example, squaring the odd number 3 gives 9, and squaring 5 gives 25, both of which are odd numbers. Thus, the pattern holds true for all odd integers.
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
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
