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?

Answer 1

The weight of the turtles together is
`500\ pounds`

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

`264+186=450\ pounds`

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
`5` (this is called rounding down)

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

In this problem we have

`450`

We want to keep the digit
`4`

The next digit is
`5` 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
`500\ pounds`
