    #1: Total amount of dimes = 18/Total amount of coins = 23; 18/23 > 1/2; Likely

    #2: Total amount of brown puppies = 1/Total amount of puppies = 6; 1/6 < 1/2; Unlikely

    #3: Total amount of mangoes = 15/Total amount of fruits = 20; 15/20 or 3/4 > 1/2; Likely

    #4: Total amount of pink ribbons = 4/Total amount of ribbons = 20; 4/20 or 1/5 < 1/2; Unlikely

    Q: How is the number 720,000,000 written in Scientific Notation?

    A: 7.2 x 108

     

    Why is 720,000,000 written as 7.2 x 108 in scientific notation?

    The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

    Calculating scientific notation for a positive integer is simple, as it always follows this notation:

    a x 10b

    Follow the steps below to see how 720,000,000 is written in scientific notation.

    Step 1

    To find a, take the number and move a decimal place to the right one position.

    Original Number: 720,000,000

    New Number: 7.20000000

    Step 2

    Now, to find b, count how many places to the right of the decimal.

    New Number:7.20000000

    Decimal Count:  12345678

    There are 8 places to the right of the decimal place.

    Step 3

    Building upon what we know above, we can now reconstruct the number into scientific notation.

    Remember, the notation is: a x 10b

    a = 7.2 (Please notice any zeroes on the end have been removed)

    b = 8

    Now the whole thing:

    7.2 x 108

    Step 4

    Check your work:

    108 = 100,000,000 x 7.2 = 720,000,000
