21
You first of all divide 28 by 4 to get 7. This is one fourth of 28. Multiply the 7 by 3 to get 21 . 21 is three fourths of 28
You need to divide it by 6/7.
2x-21 = 7 Adding 21 in both sides will change 2x-21+21 = 7 + 21 into 2x = 28 Now divide both sides on 2 2x/2 = 28/2 then x = 14
Add all of the numbers, and divide the result by how many numbers there are.21 + 17 + 14 + 28 + 15 = 9595 / 5 = 19

both numbers have a common factor of 7 divide each by 7: 21/28 = 3/4
To find the number halfway between any two numbers x and y, add x and y, then divide the answer by 2. So for 21 and 35, 21+ 35 = 56. 56/2 = 28. You can check your answer by seeing that 21 + 7 = 28 and 35 - 7 = 28.

There is 60 minutes in an hour so divide 1701 by 60. You will get 28 and 21/60. Therefore, 1701 minutes = 28 hours 21 minutes
571 divide by 28 = 20.392857142857142
divide by 21
21/28 but both 21 and 28 are multiples of 7 so you can divide top and bottom by 7. This gives you 3/4. Hope it helped :)
