There are 3
4 as many boys as girls in a class of fifth-graders. If there are 35 students in the class, how many
are girls?

Let's denote the number of girls in the class as \( g \). According to the problem, there are \( \frac{3}{4} \) as many boys as girls, which means the number of boys is:

\[
b = \frac{3}{4}g
\]

The total number of students in the class is given as 35. Therefore, we have the equation:

\[
g + b = 35
\]

Substitute \( b = \frac{3}{4}g \) into the equation:

\[
g + \frac{3}{4}g = 35
\]

Combine like terms:

\[
\frac{4}{4}g + \frac{3}{4}g = 35
\]

\[
\frac{7}{4}g = 35
\]

Multiply both sides by 4 to clear the fraction:

\[
7g = 140
\]

Now, divide both sides by 7:

\[
g = 20
\]

So, there are 20 girls in the class.

Here are some related questions:
1. How many boys are there in the class?
2. What is the ratio of boys to girls?
3. If 5 more girls join the class, what will be the new ratio of boys to girls?
4. How would the problem change if there were 5 fewer students in total?
5. If there are twice as many boys as girls in another class, how many girls would there be if there were 36 students?

**Tip:** When dealing with ratios, it's useful to express one quantity in terms of the other and then use given totals to find the values.

There are 3/4 as many boys as girls in a class of fifth-graders. If there are 35 students in the class, how many are girls?
