Answer:
2:3
Explanation:
There were 300 children in total. Of those 300, 120 are boys. To find out the number of girls, subtract 120 from 300 to get 180.
300 - 120 = 180 girls
Total: 300 || Boys: 120 || Girls: 180
Next, simply imput the numbers into your ratio.
120:180
Then, to get the shortest answer, simplify the two numbers by dividing them.
2 : 3
