several concepts about fractions. One concept students in fourth grade will need to master is learning how to tell if fractions are equivalent with unlike denominators. There are a few prerequisite skills that are necessary in order for the students to understand this concept. The first thing students need to know is what fractions are. Fractions are a way of counting parts of a whole. Secondly‚ the students need to know how to identify parts of a fraction. The top number in a fraction is the numerator

Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom‚ such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations (addition

Mole Fraction Return to Solutions Menu The mole fraction is: moles of target substance divided by total moles involved The symbol for the mole fraction is the lower-case Greek letter chi‚ χ. You will often see it with a subscript: χsolute is an example. Example #1: 0.100 mole of NaCl is dissolved into 100.0 grams of pure H2O. What is the mole fraction of NaCl? Solution: 100.0 g / 18.0 g mol¯1 = 5.56 mol of H2O Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66 mol total Mole fraction

The density of fractions 1‚ 2‚ and 3 are as follows: 1.49‚ 1.325‚ and 1.34 g/mL. These values areincorrect because the density should not have been over 1.0 g/mL. This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing

Distillations are use to purify contaminates out of water to obtain clean pure water‚ as well as‚ to separate mixtures of liquids into their individual components; e.g. methanol and water. Objective: Distill methanol from water using a simple distillation

more than $500‚000 is carried over each year‚ I would proceed to gather more information about the blood fraction from the surgeon. Why does he think the highly specialized blood fraction speeds healing time when there are no clinical studies that support his claim? I would also look at the recovery status and length of stay in hospitals for patients that have used the specialized blood fraction. If the results do not support the surgeon’s claim and there are no additional benefits for its use‚ I would

How we use fractions everyday and don ’t even realize it (Math worksheets center) If you walk down the aisles of your local mall you probably would get a third of the way there without coming in contact into a fraction in some way. After all‚ that walk down the aisle is a fraction: 1/3. Yes‚ we use fractions in one way or another in everyday life even though we may not completely realize it. For example‚ you use fractions every time you look at a clock. Yes‚ we know that quart past (1/4)‚ half

In Lacsap’s Fractions‚ En(r) refers to the (r+1)th term in the nth row. The numerator and denominator are found separately‚ therefore to find the general statement‚ two different equations‚ one for the numerator and one for the denominator‚ must be found. Let M=numerator and let D=denominator so that En(r) = M/D. To find the numerator for any number of Lacsap’s Fractions‚ an equation must be made that uses the row number to find the numerator. Because the numerator changes depending on the row
