When we add and subtract fractions, we count how many of the same size parts there are. When we multiply fractions, the sizes of the parts change. Consider this multiplication problem: . Complex. fractions are fractions that have fractions within them. They are either in the . numerator. , the denominator, or . both. .. Divide complex fractions by multiplying .

How can I apply and extend my understanding of operations with whole numbers to operations with fractions and mixed numbers including real-world situations?. Lesson 1. Our decimal system is based on powers of 10 such as 10, 100, and 1,000. If the denominator of a fraction has a power of 10, you can use place value to write the fraction as a decimal. . Write Fractions as Decimals. . Math Textbook Pages . 404-408. Objectives. I can write rates, equivalent rates, and unit rates.. I can use rate, equivalent rates, and unit rates to compare quantities. Writing a rate!. Rate: a comparison of two quantities that have different units. Jeff hikes ½ mile every 15 minutes, or ¼ hour. . Why is 15 minutes equal to ¼ hour?. How far does Jeff hike in 1 hour?. 2 hours?. Method 1 – Use a Bar Diagram. How many ¼ hours are in 1 hour?. How far does Jeff hike in 1 hour?. 1. Remember that fractions are parts of a whole or a part of a set of objects. For example, if a bag of apples contains 10 apples and three of the apples are used to make apple tarts, three-tenths, 3/10, of the apples have been used and seven-tenths, 7/10, of the original set of 10 apples remain. .
