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.
Well, sweetheart, 4 and 8 can both go into numbers that are multiples of both 4 and 8. In other words, they can both go into numbers that are divisible by both 4 and 8. So, grab your calculator and start crunching those numbers!
4 can go into both numbers. 12 divided by 4 is 3 and 32 divided by 4 is 8. 3/8
There are 4 positive and 4 negative numbers that go into 15. They are: 1,3,5,15,-1,-3,-5, and -15.
3 goes into both 27 and 12. 3 x 9 = 27 and 3 x 4 = 12
what can go into both 28 12
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.
5y - 3 = 4 + 9y Subtract 5y from both sides: -3 = 4 + 4y Subtract 4 from both sides: -7 = 4y Divide both sides by 4: -7/4 = y
(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 ■
3x + 4 = 2x - 3 Subtract 2x from both sides: x + 4 = - 3 Subtract 4 from both sides: x = -7
As 8 is even, and 3 is odd, I think only 1 can go into both.
3 can go into both.
(2x+4)/3 = 6Multiply both sides of the equation by 3:(2x+4)/3*3 = 6*32x+4=182x+4-4 = 18 -4 Subtract 4 from both sides2x = 142x/2 = 14/2 Divide both sides by 2 to solve for xx = 7
