There are three grades in the school. One grade has 1/3 of the students, one grade has 1/4 of the students. What fraction of stu
AlladinOne [14]

Answer:

Step-by-step explanation:

Let x represent the total number of stdents that has all grades in the school.

There are three grades in the school. One grade has 1/3 of the students, this means that number of students that belongs tho this grade is 1/3 × x = x/3

One grade has 1/4 of the students, this means that number of students that belongs to this grade is 1/4 × x = x/4

Total number of students in both grades would be x/3 +/x/4 = 7x/12

The number of students in the remaining grade would be

x - 7x/12 = 5x/12

fraction of students in the remaining grade would be

(5x/12)/x = 5/12

Answer:

  (C)  Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step-by-step explanation:

The first step is to eliminate the parentheses, using the distributive property.

  5(3x − 4) = 1

  15x -20 = 1

The second step is to add 20 to both sides of the equation.

  15x = 21

This pair of steps is shown in the 3rd choice.

_____

<em>Comment on the answers</em>

The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
