you put 15 marbles into 3 groups
15 marbles into 3 groups
15/3 = 5
3 groups of 5 marbles in each group
What do you want us to do?
To divide 15 marbles into 3 groups, you can follow these steps:
Step 1: Determine the number of marbles you want to place in each group. In this case, you want to put an equal number of marbles in each group.
Step 2: Divide the total number of marbles (15) by the number of groups (3). This will give you the number of marbles in each group.
15 marbles รท 3 groups = 5 marbles per group
Step 3: Place 5 marbles in each group until you have allocated all 15 marbles.
Group 1: Place 5 marbles
Group 2: Place another 5 marbles
Group 3: Place the remaining 5 marbles
By following these steps, you will have evenly divided 15 marbles into 3 groups, with each group containing 5 marbles.
