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.
what goes into both 21 and 25
2/7 is the simplest form of 6/21. To figure it out, you look at 6/21, and you notice that 3 can go into both the numerator and the denominator. So you divide them both by 3, and you get 2/7. That doesn't change the value of the fraction. It just makes it 'simpler'.
The smallest number that both 21 and 23 can go into is 483.
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.
