represent how many dolls they each have.
Draw and label Andrea's dolls with a strip diagram.
Kesa has times as many dolls as Andrea.
Draw and label a strip diagram to represent Kesa's dolls.
How many dolls does Kesa have?

Answer 1

To represent the dolls Andrea has, draw a strip diagram with 9 dolls labeled as '1.' For Kesa, draw 7 groups of 9 dolls each. Kesa has a total of 63 dolls.

Step-by-step explanation:

To represent the number of dolls Andrea has on a strip diagram, you can draw nine dolls in a row. Each doll can be labeled with the number 1 to indicate that one doll represents one unit. So, the strip diagram for Andrea's dolls would consist of nine dolls laid out horizontally, each labeled with '1.'

Strip Diagram for Andrea:

1. Doll: 1
2. Doll: 1
3. Doll: 1
4. Doll: 1
5. Doll: 1
6. Doll: 1
7. Doll: 1
8. Doll: 1
9. Doll: 1

To represent the number of dolls Kesa has, which is 7 times as many as Andrea, you can draw seven groups of nine dolls each. Each group represents the number of dolls Andrea has. So, the strip diagram for Kesa's dolls would consist of seven groups of nine dolls each, with each group labeled as 'Andrea's dolls.'

Strip Diagram for Kesa:

1. Andrea's dolls: 1 1 1 1 1 1 1 1 1
2. Andrea's dolls: 1 1 1 1 1 1 1 1 1
3. Andrea's dolls: 1 1 1 1 1 1 1 1 1
4. Andrea's dolls: 1 1 1 1 1 1 1 1 1
5. Andrea's dolls: 1 1 1 1 1 1 1 1 1
6. Andrea's dolls: 1 1 1 1 1 1 1 1 1
7. Andrea's dolls: 1 1 1 1 1 1 1 1 1

Kesa has a total of 63 dolls. This is calculated by multiplying the number of dolls Andrea has (9) by the number of groups of dolls Kesa has (7). So, 9 * 7 = 63, meaning Kesa has 63 dolls.
