    in the number:1582.9604
    tenths place is:
    thousandths place is:
    tens:
    thousands:

    write the following decimals as fractions:
    0.4=

    tenths place is: 9

    tens place is: 8
    thousands is: 1

    0.4 = 2/5
    16.01 = 16 and 1/100

    THe hundreds position is the 6 at the start (it is 600) therefore we halve that to get 3, this is our number:

    658.433

    in the number:1582.9604
    tenths place is: 9
    thousandths place is: 0
    tens: 8
    thousands: 1

    the way to work this out is to consider the number as separate bits,

    1582.9604 is the same as:

    1000 (we have 1 thousand)
    +500 (5 hundreds)
    +80 (8 tens)
    +2 (2 ones, or units)
    +0.9 (9 tenths)
    +0.06 (6 hundredths)
    +0.000 (0 thousandths)
    +0.0004 (4 ten thousandths)

    write the following decimals as fractions:
    0.4=

    We have 4 tenths. 1 tenth is 1/10 therefore 4 tenths is 4/10.


    16.01=

    We have 16 and 1 hundredth, so we have 16 and 1/100, there is no need to put this as 1 fraction, but if you did the answer would be 1601/100.


    round the number 14.538
    tenth=14.5

    When we round we take the number just after the number we want to round.
    Here we want the tenths which is 5, so we look at 3 and see if it is equal to or above 5, 3 is not therefore we round down (change it to zero), so 5 stays the same.

    ten=10

    For the tens we are looking at the 1, the number after it is 4 (which is not 5 or higher, so we round down(change it to 0), and 1 stays the same).

    I hope this helped.
