Question

Which expressions have an estimated value that is close to 12? Check all that apply.

Answer 1

We determine which expressions have a value close to 12 as follows:

`(1)/(5)\cdot60.14=12.028`
`(2)/(7)\cdot42.85=12.24285714`
`(3)/(8)\cdot31.54=11.8275`
`(4)/(7)\cdot14\cdot82=8.468571429`
`(5)/(8)\cdot9.08=9.2625`

So, the expressions with values close to 12 are a, b & c.
