    so 5 1/3 means 5 , and then 1/3 of 1

    in decimal form, that means 5.333333333

    sandra can you help me with regression when you're finished please?

    but conceptually, you can see that 5 1/3 is less than six, because 5 1/3 = 5 + 1/3 (which is less than one), and 6.7 means 5 + 1.7 (which is more than one)

    another way to compare them is to turn them both into fractions

    but let's see some other sample problems too

    for example, what is bigger, 1/2 or 1/3?

    1/3?

    nope, it's just the bottom number is bigger. let me show you how to compare

    to compare fractions, it helps to find what's called a common denominator

    for example, if I asked you what's bigger, 1/3, or 2/3, what would you say?

    Wait :) I have some numbers with decimals with them!

    ok but 2/3 is bigger than 1/3, because the top number is bigger in 2/3 than 1/3 - and they're fractions out of the same overall unit (3's)

    but go ahead and post another example with decimals

    How do convert fractions into decimals?

  26. anonymous

    well, it's easiest to make it so some power of 10 is on the bottom

  27. anonymous

    for example, 1/10 = .1 , 1/100 = .01, 1/1000 = .001 The rule is, you're allowed to move the decimal one to the left with each zero that's on the bottom

    I don't understand.

    well, 1/10 is another way of writing "one divided by ten"

  30. anonymous

    and when I divide by some power of 10 - for example 10, 100, 1000, 2000, all that means is moving the decimal point one to the left

  31. anonymous
    • 5 years ago

    so 1 divided by 10 is .1

  32. anonymous

    2 divided by 10 is .2

  33. anonymous
    • 5 years ago

    I just move the point one to the left

  34. anonymous
    • 5 years ago

    multiplying by some power of 10 means I get to move the decimal point one to the right, and add a zero

  35. anonymous
    • 5 years ago
    Best Response
    You've already chosen the best response.
    Medals 0

    so 1 x 10 = 10 (added one zero), 2 x 100 = 200 (I get to add two zeros), and 6.7 x 10 = 67 (I get to move the decimal point to the right)

    so there are two ways to compare a decimal and a fraction

  37. anonymous

    one way would be to convert the fraction to a decimal - and then compare them

  38. anonymous

    another way would be to convert the decimal to a fraction, and then compare those fractions

  39. anonymous

    I imagine they want you to learn the second approach

  40. anonymous

    now to compare fractions, as I was saying earlier, you need to find what's called a "common denominator"
