3. The quotient of two numbers is the result of division. In this case, 21 is the dividend, or the number being divided, and 7 is divider, or the number doing the dividing.
21 : 7 = 42 : 14
7
The three numbers that equal 21 are 7, 7, and 7. This is because when you add 7 + 7 + 7, you get 21. In mathematical terms, this can be represented as 7 x 3 = 21, where 7 is multiplied by 3 to achieve the total of 21.
Yes, 21 can be divided into equal groups. 21 is divisible by 1, 3, 7, and 21. Therefore, you can divide 21 into 1 group of 21, 3 groups of 7, 7 groups of 3, or 21 groups of 1, with each group being equal in size.
21
21 divided in to 3 equal parts = 7
1 x 21 3 x 7 7 x 3 21 x 1
21 + 7 = 28
Yes, 7 X 3= 21.
A = 7. 4a + 3 - a = 24 4a - a = 21 3a = 21 a = 7
You can do 7 times 3 and that will equal 21
7 + 7 + 7 = 21
