Ming has 13 rocks. He puts them into 2 equal groups with some left over. How many rocks are in each group?
Six rocks are in each group, with one rock leftover.
6(2) = 12 + 1 = 13
Of course, 6 is just the largest group size. He could have made two groups of 3, with 7 left over.
To find the number of rocks in each group, we need to divide the total number of rocks by the number of groups.
In this case, Ming has 13 rocks which he puts into 2 equal groups. Since there are some rocks left over, it means that the rocks cannot be divided equally into 2 groups.
To determine the number of rocks in each group, we can start by dividing the total number of rocks (13) by 2.
When we divide 13 by 2, we get a quotient of 6 and a remainder of 1.
This means that Ming can put 6 rocks in each group, and there will be 1 rock left over.
So, there are 6 rocks in each group.
