Question 2 (request help) 738 - 227 Estimate: Difference:

Answer 1

round 738 up to 740...round 227 up to 230
740-230=510 estimate

Answer 2

`500`

Explanation:

In order to estimate difference for two given numbers, we round each number to the nearest multiple of
`100` and perform subtraction with the new rounded number.

∴ by rounding
`738` we will obtain
`700` and by rounding
`227` we will obtain
`200`

Now performing subtraction between these rounded numbers, we will get-

`700 - 200 = 500`

∴ Estimate difference between
`738` and
`227` will be
`500`
