To find out how many groups of 7 equals 21, you can divide 21 by 7. The result is 3, which means there are 3 groups of 7 in 21. This is because when you multiply 7 by 3, you get 21. So, there are 3 groups of 7 that equal 21.
There are three possibilities:-- 7 equal groups, with 3 in each group-- 3 equal groups, with 7 in each group-- 21 equal groups, with 1 in each group
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.
Yes. It can be divided into -- 21 equal groups of 1 each -- 3 equal groups of 7 each -- 7 equal groups of 3 each
7 multiplied by 3 equals 21. Multiplication is a mathematical operation that combines groups of equal numbers to find a total quantity. In this case, you are taking 7 groups of 3 and finding the total quantity, which is 21. The multiplication symbol "x" is used to represent this operation.

21 and 2/3
There are 3 feet in one yard. Therefore, 21 feet is equal to 21 / 3 = 7 yards.
1 yd= 3ft 21/3= 7 yards
21 divided in to 3 equal parts = 7
