Answer:
105 girls
Step-by-step explanation:
The ratio between girls and boys is 3:4, which means for every 3 girls, there are 4 boys. We are trying to solve for the number of girls, so the ratio will be x:140. First let's divide 140 by 4 to find out the value of each part.
We will get 35 for each part.
Multiply 35 by 3 to get 105. There we find that there are 105 girls for 140 boys. Hope this helped :)
