Question

Can y’all help me on my last practice problem

Answer 1

There are 24 girls on the field trip.

Explanation:

1. Organizing the Information

This is a percentage problem. There isn't too much information to take in here, but having the numbers laid out concisely will make things much easier.

Boys = 36

Girls = x

36 = 60%

x = 40%

2. Creating the Equation

Using this information, create an equation to find the total amount of students.

In this case, create an equation to find 10% of the total.

60% will be converted into 6y.

y will represent 10% of the total.

The finished equation is:

36 = 6y

3. Solving the Equation

Using the order of operations, solve the equation.

36 = 6y

36/6 = y

6 = y

y was meant to represent 10% of the total.

Taking into account that y = 6, multiply 6 by 10 to calculate the total.

The total is 60.

4. Solving for x

If the total is 60, it should be much easier to solve for x now.

As said previously, x is equal to 40% of the total.

To solve for x, convert 40% into a decimal. The decimal should be 0.4, or 40% of 1.

Multiply 60 by 0.4 to find 40% of 60.

The answer is 24.

24 girls are on the field trip.

Answer 2

If 40% of the students are girls then that means 60% of the students are boys.

First, turn 60% into a decimal.

60% = 0.6

Second, divide by the number of boys.

36 / 0.6 = 60 total students

Third, turn 40% into a decimal.

40% = 0.4

Fourth, multiply by the total number of students.

60 * 0.4 = 24 girls

Best of Luck!
