Answer:
80% of the students passed the algebra test
Step-by-step explanation:
So for this question, they want to know the percentage of the people that passed.
20 out of 25 students passed, we could find the percentage using two ways:
-------
1. We can use proportions to figure out the percentage (This can only work if the numbers are factorable by 100 such as 10, 25, 50...)
25 × 4 would equal 100. You must multiply the same number to the top as well.
So 20 × 4 = 80
--------
2. We can divide the two numbers
20 ÷ 25 = 0.8
When changed into a percentage, 0.8 would be 80%
-------
Have a good day :)
