Answer is in attached image.

Step-by-step 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.
