Question

Evelyn sold 11 boxes of chocolate cookies. Each box contained 12 cookies. Round to the nearest ten and then multiply to find the total number of cookies.

Answer 1

Answer: 100 cookies approximately.

Explanation:

To round to the nearest ten:

- If the digit located in the units place of the number is
`<5`, then you must round the number down.

- If the digit located in the units place of the number is
`\geq5`, then you must round the number up.

The digit located in the units place of the number 11 is 1 and
`1<5`, therefore you must round the number down to: 10

The digit located in the units place of the number 12 is 2 and
`2<5`, therefore you must round the number down to: 10

Multiply 10 by 10 to estimate the total number of cookies:

`Total_((cookies))=10*10\\Total_((cookies))=100`

(100 cookies approximately)
