Making up a Division Word ProblemDate: 11/13/2001 at 22:30:29 From: ashley gooden Subject: Word problem Write a problem that could be solved by using the division sentence 1489/28 = n. Then write a pair of compatible numbers and estimate the quotient. Grandma and I don't understand. Thank you for your help, Ashley Date: 11/15/2001 at 10:57:25 From: Doctor Code Subject: Re: Word problem Hi Ashley, Let's use a slightly different problem as an example: 1194 / 32 = n What we have to do is come up with a word problem that can be solved with the above division sentence. How about this: Your teacher has 1194 jellybeans to give to the class. The class has 32 students. If the teacher gives them out about equally, how many jellybeans will each student get? If you were given this word problem, you could find the answer by dividing 1194 by 32. That's why the division sentence can solve the problem. But 1194 and 32 aren't such nice numbers to divide, so we can estimate the solution by changing 1194 into 1200, and changing 32 into 30. Our new division sentence would be: 1200 / 30 = n 40 = n So each student would get about 40 jellybeans. 40 is pretty close to the actual answer (37.3125). Now try the same method with your original sentence. Write back if you need more help. - Doctor Code, The Math Forum http://mathforum.org/dr.math/ |
