List numbers that multiply to make 28 and find their sums. Since negative times a negative is positive, list the negatives. -1, -28 = -29 -2, -14 = -15 -4, -7 = -11 Aha! -4 and -7 multiply to make 28 and add to -11; therefore, -4 and -7 are the two numbers.
28
How about: 2+6+8+12 = 28 as one example
4/7-3/4= firs you want to get both numbers to have the same denominator and 7 and 4 are both multiples of 28, so make 28 the demoninator. 4/7-3/4= ?/28-?/28 <<< so what times 7 gives you 28 and what times 4 gives you 28? you use that answer to replace the question mark, but you have to multiply it by the numbers that were already in the numerator (3 and 4). so now you have 4(4)/28-3(7)/28= 16/28-21/28=-5/28
The numbers are 4 and 24 because 24/4 = 6 and 4+24 = 28

1 and 28. 2 and 14. 4 and 7.
((7-2) * 4) + 8 = (5 * 4) + 8 = 20 + 8 = 28

The numbers are 4 and 24 because 24/4 = 6 and 4+24 = 28
Since 4 and 28 are composite numbers, then any of their multiples are also composite.
Well, darling, I'm not here to play games, but I'll humor you this one time. The two square numbers that add up to 64 are 36 and 28. Don't come crying to me if you can't handle the heat in the math kitchen.
