Let us suppose, we pour x glass of water.
The given jug is of 6 liters. And the glass of water was seven- eighths of a liter. Hence, we have the below equation
Now, in order to solve for x, we will divide 6 with 7/8. So, we have to divide.
Hence, we can pour 7 glass of water. But the 7th glass is not full of water. It is partially full.
So we solve for each
70% of 100=70
students who didn't buy lunch=100-70=30
some of the 70 left so that the students who bought lunch, are 60% of those who are left
we know that the students who didn't buy lunch didn't change number so therefor
100% of students left-60%=40%= students that didn't buy lunch=30 so
40%=30
20%=15
100%=75
there were 75 students lfet in the cafeteria
Area of a rectangle is length x width.
So the area is 15000 because 150 x 100 = 15000
