Question

5. Green sea turtles can grow to be more than 3 feet long. The
aquarium has one sea turtle that weighs 264 pounds and a younger
turtle that weighs 186 pounds. To the nearest hundred, what is the fa
weight of the 2 sea turtles together?

1 Answer

  • Answer:

    The weight of the turtles together is [tex]500\ pounds[/tex]

    Step-by-step explanation:

    we know that

    To find out the weight of the 2 sea turtles together, adds the weight of one turtle plus the weight of the other turtle and then round to the nearest hundred

    step 1

    Adds the weight of the two turtles

    [tex]264+186=450\ pounds[/tex]

    step 2

    Round to the nearest hundred

    Remember that

    To Round a number

    a) Decide which is the last digit to keep  

    b) Leave it the same if the next digit is less than [tex]5[/tex] (this is called rounding down)  

    c) But increase it by  [tex]1[/tex] if the next digit is  [tex]5[/tex] or more (this is called rounding up)

    In this problem we have

    [tex]450[/tex]

    We want to keep the digit [tex]4[/tex]

    The next digit is [tex]5[/tex] which is 5 or more, so increase the "4" by 1 to "5"

    therefore

    The weight of the turtles together round to the nearest hundred is [tex]500\ pounds[/tex]
