Improper fractions contain a numerator that is equal to or greater than the denominator. These fractions are described as improper because a whole number can be pulled out from them, yielding a mixed number fraction. This mixed number fraction is a simplified version of the number and, therefore...
How do you solve for mole fraction, density and %w/w, when you are given Cr2(SO4)3, with molarity of 1.26 M and molality of 1.37 m? Concentration Units: Both concentration units of molarity and molality are expressed in moles sol...
A two-step algebra equation is an important concept in math. It can be used to solve problems that are not as simple one-step addition, subtraction, multiplication or division ones. In addition, fraction problems add an additional layer or computation into the problem. Step 1 Examine a proble...
represents how many parts make up a whole. The numerator, or top half of the fraction, represents how many parts are being discussed. Students often have trouble understanding the concept of fractions, which can lead to difficulty completing fraction problems. The more the students practice with ...
