Final answer:
The ratio of girls to boys is 2:7.
Step-by-step explanation:
The ratio of girls to boys can be found by dividing the number of girls by the number of boys. In this case, there are 10 girls for every 35 boys. So the ratio can be written as 10:35. However, we can simplify this ratio by dividing both numbers by their greatest common factor, which is 5. Therefore, the simplified ratio of girls to boys is 2:7.
The question asks us to write the ratio of girls to boys when there are 10 girls for every 35 boys. To find this ratio, we simply compare the number of girls to the number of boys using a colon or fraction to express their relationship. In this case, the ratio is 10:35 or alternatively as 10/35, which can be simplified by dividing both numbers by their greatest common divisor. The greatest common divisor of 10 and 35 is 5. Therefore, when simplified, the ratio becomes 2:7. This means for every 2 girls, there are 7 boys.
