Approximately 28% of the students in the class did extra credit to improve their grade. If there are 26 students in the class, how many students did extra credit?
Remember that percent is how many per 100. We can write this as a decimal by taking the percent and dividing by 100. That means that 28% is 28/100 = 0.28. If you multiply this by how many students there are, you can find out how many did the extra credit. 28% of 26 .28 * 26 7.28 Since we can't have part of a student, we have to round to the nearest whole number. This gives us an answer of 7 students.

If we flip fractions when finding reciprocals, how do you find the reciprocal of a whole number like 5 or 8?
Remember that almost all numbers can be written as a fraction. 5 is really just 5/1 and 8 is 8/1. That means the reciprocal of 5 is 1/5 and 8 is 1/8.
Describe two real-world situations where inequalities can be observed and write them as a mathematical expression.
In order to ride certain roller coasters, people must be at least 48 inches tall. If h represents height, then h≥48. I only have $25 dollars to spend on groceries for dinner. If c is the cost of my groceries, then c≤25.
