19/20, because when you divide 19 into 20 you get... 0.95
The sixth grade makes 3.09 per hour
The seventh graders make 2.54 per hour
the eighth graders make 2.90 per hour
So the sixth graders make the most per hour. you can check this answer by taking the amount of money made and divide it by the time that it takes to raise the total amount of money raised by each class of students.
Two fractions equivalent are 18/20 & 27/30
The number is 14
Here's the solution:
Let the number be x
According to the question,
27+7x=125
//Subtract 27 from both the sides
7x=125-27
7x=98
//divide both the sides by 7
x=98/7
x=14
