x=1.15z
y=1.25z
And then:
1.15z/1.25z=1.15/1.25=0.92=92%

Percentage is a way of expressing a portion or fraction of a whole number as a number out of 100. It is often denoted by the symbol "%".
To calculate a percentage, divide the part by the whole and multiply by 100. For example, if you want to find 25% of 80, you would divide 25 by 100 and then multiply by 80, giving you a result of 20.
Percentages are used in many different fields, including finance, statistics, and science. Some common examples of real-life applications of percentages include calculating discounts, analyzing data, and determining success rates.
Percentages can be used in various homework assignments, such as calculating grades, solving word problems, and analyzing data. They can also be used to demonstrate understanding of mathematical concepts and as a tool for problem-solving.
To better understand percentages, it can be helpful to practice converting between percentages, fractions, and decimals. It is also important to understand the relationship between percentages and the concept of "out of 100". Additionally, visual aids, such as diagrams and charts, can be useful in understanding percentages.
