When you're solving fractions, you sometimes need to work with fractions that are over other fractions. This can seem daunting at first, but it's actually not too difficult once you understand the process. Here's a step-by-step guide to solving fractions over fractions. First, you need to find a common denominator for both of the fractions involved. The easiest way to do this is to find the least common multiple of the two denominators. Once you have the common denominator, you can rewrite both fractions so they have this denominator. Next, you need to add or subtract the numerators of the two fractions in order to solve for the new fraction. Remember, the denominators stays the same. Finally, simplify the fraction if possible and write your answer in lowest terms. With a little practice, you'll be solving fractions over fractions like a pro!

How to solve for x in a right triangle To find the value of x, use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. In other words, if you know the lengths of two sides of a right triangle, you can find the length of the third side by using this equation: a^2 + b^2 = c^2. To solve for x, plug in the known values for a and b, and then solve for c. For example, if you know that a = 3 and b = 4, then you can solve for c like this: 3^2 + 4^2 = c^2 9 + 16 = c^2 25 = c^2 c = 5 Therefore, in this example, x = 5.

How to solve mode? There are a couple of different ways that you can go about solving for mode. The first method is to simply find the number that appears most often in your data set. To do this, you can either use a tally chart or a frequency table. Once you have tallied up the frequencies, the mode will be the number with the highest frequency. The second method is to use the mean and median to solve for mode. To do this, you first need to find the median of your data set. Once you have found the median, look at the numbers on either side of it. The mode will be the number that appears most often in this range. If both numbers appear equally often, then there is no mode for your data set.

A linear algebra solver can be used to find the solutions to systems of linear equations. Additionally, it can be used to find the inverse of a matrix, determinants, and eigenvectors. Linear algebra solvers are a valuable tool for mathematicians and engineers alike. Whether you're solving simple equations or working with more complex mathematical models, a linear algebra solver can be an invaluable resource.

The app is super useful when I don’t understand how to complete and problem, or where I may have gone wrong on one. It works perfectly, though there are still some problems that it can’t solve yet- But I believe it deserves 5 stars. -Jax

The second-best application I've ever downloaded after Duolingo. I was quite stressed out when I had to take college algebra for college but with the app, I've literally been able to get everything in math as well as understand it. Amazing application only reason I've managed to get through the past three months of college algebra. Merci beaucoup. 🥰 *if you want to use it accurately it's best to write down the solutions by hand on a book for ease of use*
