Determine if 20 rolls for $5 and 48 rolls for $12 are equivalent rates. . 1. st. Write . each rate as a fraction. . 2. nd. Find . its unit rate.. =. 20 rolls. $5. __________. Standard 4NF1. Say What?. Let’s try it with numbers instead of letters.. ½ is equivalent to (2 x 1) / (2 x 2). So, ½ is equivalent to 2/4.. The Goose/Gander Rule. With equivalent fractions, there is always one important rule that must be followed.. I can identify the products and reactants in a chemical reaction.. I can state the law of conservation of matter.. I can determine the number of each atom in a compound based on subscripts and coefficients.. Standard: . 8.EE.C.. 7b . Solve . linear equations in one variable. . Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms. . Fractions the same as a ½. . Look at the shapes below, they all have ½ shaded but the half could be written in different ways.. 1/2 . 2/4. 3/6. 4/8. Look at those fractions again!. . 1. . 2. . Problem 1. There are 25 toys in a playground. . The toys are either bicycles (2 wheels) or tricycles (3 wheels). . In total in the playground there are 61 wheels. . How many bicycles are in the playground?. By graphing. Definition. A system of linear equations, aka linear system, consists of two or more linear equations with the same variables.. x + 2y = 7. 3x – 2y = 5. The solution. The solution of a system of linear equations is the ordered pair that satisfies each equation in the system. . Ratios and Rates. Objective:. Learn to find Equivalent Ratios and Rates. . Equivalent Ratios and Rates. You can find equivalent ratios and rates the same way as you find equivalent fractions- by multiplying or dividing both parts of the ratio or rate by the same number.. For. example:. In this . lesson, . you . will learn how to identify equivalent fractions. . by . using a number line.. Fractions. 0. 1. Thinking fractions with different numerators and denominators are not equivalent. Which is an equivalent fraction? .  . A. . B. . C. . D. .  . Which is an equivalent fraction? .  . A. . B. . C. . D. .  . Which is an equivalent fraction? .  . A. . B. . C. . D. .  . 1. 2. Elementary Row Operations. There are three kinds of Elementary Row Operations.. 1) Interchanging two rows.. Multiplying a row by a non-zero constant.. Adding a multiple of one row to another row.. Exercise 1. Circle any equivalent ratios from the list below. . Ratio: 1:2 . Ratio: 5:10 . Ratio: 6:16 . Ratio: 12:32.  . Find the value of the following ratios, leaving your answer as a fraction, but re-write the fraction using the largest possible unit.. Examples:. . 1). . . x 3 = 15. . 2) p – 5 = 20. 3) 2d = 16. 4). . = 24.  . Multi-Step Equations. Examples—. 5). 2p 15 = 29. 6). 14 – 3n = -10. 7). 27 = -9(y 5). 8). 7a – 3a 2a – a = 16.
