People who study landfills have estimated the percent of landfill space (volume) taken up by paper, food, plastic, and so on. (Think of it this way: For every 100 boxes of garbage hauled to the dump, expect that about 50 boxes could be filled with paper, 6 with metal, 1 with glass, and so on)
Space in landfills taken up by:
Paper . . . . . . . . . . . . . . . . 50%
Food and yard waste . . . . . .13%
Plastic . . . . . . . . . . . . . . . . 10%
Metal . . . . . . . . . . . . . . . . . 6%
Glass . . . . . . . . . . . . . . . . . . 1%
Other waste . . . . . . . . . . . . . .20%
7. Convert the following fractions to decimals and percents. Round to the nearest whole percent.
Fraction Decimal Percent (rounded to the nearest whole percent) 3/4 14/16 15/25 17/20 3/8
8. Complete the following open response: Sue and Kate each bought a pie. Both pies had been cut into 8 equal pieces. Sue ate 1/4 of her pie. Kate ate 3/8 of her pie.
a. Which girl ate the most pie?
b. Explain in detail how you came up with the answer to part A. Show your work.
Our Unit 4 Test is scheduled for Monday, December 8.
1. "Friendly numbers" - Remember that you can break numbers such as 72 divided by 3 into "friendly numbers" such as 60+12. 3 goes into 60 -- 20 times and 3 goes into 12 --4 times so the answer is 24 (20 + 4).
Practice doing that with other numbers such as: 56 divided by 4 (find friendly numbers for 56 that 4 will go into)
129 divided by 3
2. Practice long division with one, two, and three digit divisors.
3. Practice making estimates to division problems with decimals and then dividing with decimals...don't forget to line up your numbers and write neatly. Also remember that you can correct a division problem by multiplying the quotient by the divisor and you should get the dividend. (practice your vocabulary)
4. Work on interpreting remainders...know when to ignore them, when to report the remainder as a fraction or decimal, or when to round the answer up.
