 Elizabeth's Blog This blog is for Miss Jovanovich's algebra and geometry classes to share ideas, ask questions, and reflect on what skills and topics we are studying. If we are lucky, we might even get a chance to connect with other students studying the same stuff.

For example, how many to litres to  4 gallons, and how many feet in 3 miles, etc... So today we are writing our own problem, mine is below.    Megan has 400 German Marks and wants to fly to Mexico City, Mexico, on a purple plane. She needs to find out how many pesos are in 400 german marks. Article posted March 5, 2012 at 11:26 AM GMT • comment • Reads 624

My problem was how much is 51,197 Euros in Russian Rubles? This is how you would write out the problem...(51,197 Euros/1)(1 US/0.75 Euros)(29.80 Rubles/1 US). Then you would cross out what you can...(51,197 Euros/1)(1 US/0.75 Euros)(29.80 Rubles/1 US)...which would be the 1, the 1 US, the 0.75 Euros, and the other 1 US. You then have to multiply the top numbers and you would get an answer of 1,525,670.6. Then you would multiply the bottom numbers and get an answer of 0.75. After that, you would divide the bottom number by the top...1,525,670.6/0.75=2,034,227.47. 51,197 Euros is 2,034,227.47 Russian Rubles.

The problem I created was "If a tree is 120 feet tall, what is it's height in miles?" To solve this you just need to convert feet into miles. (120ft)(1miles/5280feet) by doing this, this cancles out feet and leave soyu with miles so on paper you would just multiplty the top row which leaves with the answer of .0227miles.

How many ounces of fan mail does he receive a minute?  (2tons/1) (2000lbs/1ton) (16oz/1lb) ---> 64,000 ounces of fan mail a month.  (64,000oz/1week) (7days/1week) (24hrs/1day) (60min/1hr) ---> 645,120,000 ounces/min Article posted March 5, 2012 at 01:59 AM GMT • comment • Reads 335

My corresponding answer to this instruction read: "The bookcase I bought at a yard sale is about 2 yards high. Approximately how tall is my bookcase in centimeters?" In order to solve this question, you must figure out how many feet are in 2 yards, then convert the amount of feet into inches, and then into centimeters. The process will look something like this: (2 yards) ----------- (6 feet) ^^3 feet are in one yard, so by doubling the amount of yards and feet it would equal 6 feet in 2 yards! (6 feet) ------------ (72 inches) ^^12 inches are in 1 foot, so by multiplying 12 by 6 (equaling 72) you would be able to figure out how many inches are in 6 feet. The answer is 72 inches in 6 feet! (72 inches) -------------------- (182.88 centimeters) ^^Since (approximately)2.54 centimeters are in 1 inch, you would multiply 2.54 by 72 and get an answer that equals 182.88. So… 182.88 centimeters would equal 72 inches! And there…Problem solved! As you can see, the final product of this conversion process would be 182.88 centimeters. So by seeing the process broken down, you now know that 2 yards is equal to 182.88 centimeters! Hope you enjoyed this little walk through about solving this particular conversation problem! –Alli :) Article posted March 1, 2012 at 01:37 AM GMT • comment • Reads 228
