Final answer:

There are a total of 240 students in the group, with 120 boys and 120 girls.

Explanation:

To find the total number of students in the group, we need to add the number of boys and girls. Since there are 120 boys, we can represent this number with a tape diagram using 120 equal parts. Similarly, we can represent the number of girls with another tape diagram using 120 equal parts. When we combine these two tape diagrams, we get a total of 240 equal parts, representing the total number of students in the group.

To visualize this better, let's divide the tape diagrams into smaller equal parts. We can divide each tape diagram into 10 equal parts, representing 10 students in each part. Therefore, the first tape diagram will have 12 equal parts (120 boys divided by 10), and the second tape diagram will also have 12 equal parts (120 girls divided by 10). When we combine these two tape diagrams, we get a total of 24 equal parts, each representing 10 students. Therefore, the final answer is 240 students in the group, with 120 boys and 120 girls.

We can also solve this problem using multiplication. Since there are 120 boys and 120 girls, we can represent this as 120 x 2 = 240. This means that we need to multiply 120 by 2 to find the total number of students in the group. This method can be useful when dealing with larger numbers, as it is a quicker and more efficient way of finding the total.

In conclusion, to find the total number of students in the group, we can use tape diagrams to represent the number of boys and girls. We can also use multiplication to find the total when dealing with larger numbers. In this case, the final answer is 240 students, with an equal number of 120 boys and 120 girls.
