The ratio of the number of girls to the total number of children is 7 : 16.
<h3>
Ratio is defined as follows:</h3>
- It is a comparison between two or more numbers that measures sizes in relation to each other
- It describe how much of a thing is compared to another.
The number of girls in the playground = 7
The number of boys in the playground = 9
The total number in the playground is the sum of the number of girls and the number of boys.
Therefore,
total children in the playground = 7 + 9 = 16
The ratio of the number of girls to the total number of children can be express as follows:

Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²
