it is 504
504 = 18 x 28 = 28 x 18 252 = 9 x 28 = 14 x 18
3 x 6 = 18
28-18=10 or 18-28= -10
Prime factorization of : 28 = 2 x 2 x 7 18 = 2 x 3 x 3
2 :)x This is how you can work it out: 18: 1,2,3,6,9,18 (These are the numbers that 18 and 28 go into.) 28: 1,2,4,7,14,28 So the highest common factor of 18 and 28 is 2. Hope it helps :)
3 x 5 = 15 2 x 3 x 3 = 18 2 x 2 x 7 = 28 2 x 2 x 3 x 3 x 5 x 7 = 1260, the LCM
2 x 3 x 3 = 18 2 x 2 x 7 = 28 Select the highest amount of each factor. 2 x 2 x 3 x 3 x 7 = 252, the LCM
18 and 10 18 x 10 = 180 18 + 10 = 28
A number x added to 18 would be written x + 18. The value* of x + 18 would depend on the value x. For example, if x was 2, x + 18 would equal 20. if x was 10, x + 18 would equal 28, and so on. *'Value' means what actual number it comes to.
To find what x multiplied by 7 equals 28, you can set up the equation 7x = 28. To solve for x, divide both sides by 7: x = 28 / 7. Simplifying, x = 4. Therefore, 4 multiplied by 7 equals 28.
30 x 0.6 = 18
18 x 28 = 504. 504 / 144 = 3.5
