what goes into both 21 and 25
The smallest number that both 21 and 23 can go into is 483.
3X + 6 = 21 subtract 6 from each side 3X = 15 divide both sides integers by 3 X = 5 =======check 3(5) + 6 = 21 15 + 6 = 21 21 = 21 ========checks
It is 21 because 21/21 = 1 and 21/7 = 3
21 6's go into 126.

The smallest number that both 21 and 23 can go into is 483.
To convert the mixed number 6 21 into a fraction, you first multiply the whole number (6) by the denominator of the fraction (21), which equals 126. Then you add the numerator (21) to get 147. So, 6 21 is equivalent to the fraction 147/21. To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 21. Therefore, the simplest form of 6 21 is 7/1.
21 ÷ 6 = 3 with remainder 3 or 3.5
1 and 3 will go into both numbers evenly with no remainders
It would be 6 think about it
you can see that both are even, so 2 will go in and you get 6 and 21. with 6 and 21, 2 won't go in, but another 3 will, giving you 2 and 7. You then can't go any further. so you got a division by 2 and then by 3 so multiply these and you get 6, your highest common factor
3X + 6 = 21 subtract 6 from each side 3X = 15 divide both sides integers by 3 X = 5 =======check 3(5) + 6 = 21 15 + 6 = 21 21 = 21 ========checks
6 + n < 21 Subtracting 6 from both sides: n < 15
It is 21 because 21/21 = 1 and 21/7 = 3
21 6's go into 126.
