Answer 1

Answer is in attached image.

Explanation:

Given the expressions, for which we have to find the estimates as per the expressions on the left.

The given expressions are:

1) 35
`*` 23

2) 132
`/` 168

3) 17.3
`*` 18.4

4) 999
`/` 208

5) 998
`*` 211

Here, we need to find the rounded off numbers.

35 can be rounded to 40 and 23 to 20.

Therefore, equivalent to 35
`*` 23 is 40
`*` 20

132 can be rounded to 130 and 168 to 170.

Therefore, equivalent to 132
`/` 168 is 130
`/` 170.

17.3 can be rounded to 17.0 and 18.4 to 18.0.

Therefore, equivalent to 17.3
`*` 18.4 is 17.0
`*` 18.0.

999 can be rounded to 1000 and 208 to 210.

Therefore, equivalent to 999
`/` 208 is 1000
`/` 210.

998 can be rounded to 1000 and 211 to 210.

Therefore, equivalent to 998
`*` 211 is 1000
`*` 210.
