Final answer:
By converting the ratio of boys to girls into fractions and using the total number of children, we can calculate that there are 65 girls among the 104 children.
Step-by-step explanation:
To determine the number of girls in a group where the ratio of boys to girls is 3 to 5 and there are 104 total children, we can use the concept of ratios and proportion.
Here are the steps to find the number of girls:
Convert the ratio into fractions: 3/8 of the children are boys and 5/8 are girls, as the ratio 3:5 totals 3+5=8 parts.
Calculate the total number of girls by multiplying the total number of children by the fraction representing girls: 104 × 5/8.
Perform the multiplication: 104 × 5/8 = 13 × 5 = 65. Thus, there are 65 girls in the group.
So, using these steps, we conclude there are 65 girls among the 104 children.
