Math

When reading the text of a word problem we can decide which operation to use when combining quantities by: i) understanding what the result of a particular mathematical operation represents and ii) making sense of the relationship being described in the problem. To elaborate, . The result of adding c and d produces the sum of c and d. . The result of subtracting d from c produces a difference that represents how much larger c is than d. . The result of multiplying c times d produces c copies of d, or a value that is c times as large as d, or a value that is d times as large as c. . The result of dividing c by d produces the relative size of c and d. By this we mean that the result tells you how many times as large c is than d. We can also say that the result is the value of c measured in units of d. Apply the above guidelines when answering each part of the following questions. Write an expression to represent each of the following relationships. a. How much taller Porter is than Henry, given that Porter is n inches tall and Henry is m inches tall. Preview b. How many times as large 6 is than 2. Preview c. How many times as tall Porter is than Henry, given that Porter is n inches tall and Henry is m inches tall. Preview d. How many times as tall Henry is than Porter, given that Porter is n inches tall and Henry is m inches tall. Preview e. The actual number of COVID-19 cases is 10 times as large as the number of positive test cases, x. Preview f. How many hundred thousand people living in the world are living in poverty, given that n people in the world are living in poverty. (Hint: How many times larger is n than 100,000)? Preview
