Presentation Transcript

1. Factoring and LCM pages: 2-5

2. Find all the factors of 60. Factors are all numbers that divide evenly into the stated number

3. Find the prime factorization of 60. Prime Numbers are numbers divisible by only 1 and itself. Factorization are numbers multiplied that equal the stated quantity

4. Find the multiples of 3. Multiples of a number all have the number as a factor. (just add itself)

5. Find the LCM of 18, 24, and 40.

6. The Earth, Jupiter, Saturn, and Uranus all revolve around the sun. The Earth takes 1 yr, Jupiter 12 yr, Saturn 30 yr, and Uranus 84 yr to make a complete revolution. On a certain night, you look at those three distant planets and wonder how many years it will be before they have the same position.

8. Fraction Notation (operations with fractions) pages: 8-15

9. Any number can be written as a fraction. The whole number 8 can be written as

10. Equivalent means the same as equals

11. Multiply and Simplify

12. Multiply and Simplify

13. Hwk: p16, 10-18, 32-62 every 3rd

14. Decimal Notation pages: 18-23

15. 0.1 0.01 0.001 0.0001

16. Analyze patterns 4.2 x 10 = 42 23.68 x 100 = 2368 0.072 x 1000 = 72

17. Divisor is not a whole number.

18. Converting from fractions to decimals. Convert 5/16 to a decimal.

19. Without rounding... With rounding (tenths, hundredths, thousandths)...

20. Keep in mind you may also do things like, round to the nearest cent, year, mile, etc.
