It is a pattern. Go up two numbers, go down two numbers.

1 and 3. These are the only whole numbers to go into both 27 and 30.
You divide each number by a number that can go into both of the numbers evenly. Say a fraction is 15/20, you can divide both numbers by 5. So it would be 3/4. So 15/20 = 3/4. 15/18 divided by 3 you get 5/6 which is the lowest term.
3 is a prime number. 4 and 10 are both composite numbers having 2 as a factor.
1 is the only whole number that can go into both 3 and 4 with no remainder.
There are 4 positive and 4 negative numbers that go into 15. They are: 1,3,5,15,-1,-3,-5, and -15.
3
Four goes into both 12 and 4. Four goes into 12 three times, and into 4 once. 12/4 = 3 4/4 = 1
15 and 20 would both go into 60. Or 300. And several others.
36
(25x + 3) = (x-3) subtract an x from both sides. 24x + 3 = -3 subtract 3 from both sides. 24x = -6 divide both sides by 24. x = -(6/24) reduce x = -(1/4) Check: 25 (-1/4) + 3 = (-1/4)-3 -25 / 4 + 3 = -1/4 - 3 -25 / 4 + 12 / 4 = -1/4 - 12/4 -13 / 4 = -13 / 4 ■
12. 12 is evenly divisible by both 12 and 4.
No they are both the same: 3/9 = 1/3 ( divide both parts by 3) as 4/12 = 1/3 (divide both parts by 4)
(2x-3)/4 = 9 2x-3 = 36 (multiply both sides by 4) 2x = 39 (add +3 to both sides) x = 19.5 (divide both sides by 2)
432/3 = 144 432/4 = 108 432 is divisible by both 3 and 4.
3 Goes in to of 12 and 15 because 3 times 5 is 15 and 3 times 4 is 12!...So there u go...I hope I answered ir question!....Have a nice day! =)
