Answer 1

Problem Analysis

We are given the following information: - 3/5 of the students went to the museum. - 3/10 of the students went home. - 18 students remained in the class.

We need to find the total number of students in the class.

Solution

Let's assume the total number of students in the class is x.

According to the given information: - 3/5 of the students went to the museum, which means (3/5)x students went to the museum. - 3/10 of the students went home, which means (3/10)x students went home. - 18 students remained in the class.

We can write the equation based on the given information: (3/5)x + (3/10)x + 18 = x

To solve this equation, we can simplify it by multiplying all terms by 10 to eliminate the fractions: 6x + 3x + 180 = 10x

Combining like terms: 9x + 180 = 10x

Subtracting 9x from both sides: 180 = x

Therefore, the total number of students in the class is 180.

Answer

There are a total of 180 students in the class.
