Answer:
0.3 galloons of water.
Step-by-step explanation:
We know that 1/5 galloons of water fills 2/3 of the bin.
So, we can write the following fraction:
We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:
To find our answer, we need to solve for x.
So, let's cross-multiply. This yields:
Multiply both sides by 3:
The left side simplifies. Multiply on the right:
Now, multiply both sides by 1/2:
Simplify the left. Multiply on the right:
So, 3/10 of 0.3 of a gallon of water will fill the entire bin.
And we're done!
Given:
Total students = 60
Student passed = 85%
To find:
The number of students who failed and then convert it in %.
Solution:
We have,
Number of passed student = 85% of Total students
=
=
So, number of passes students is 51.
Number of students who failed = Total students - Passes students
=
=
So, number of students who failed is 9.
Therefore, 15% students fail in the test.
