Answer 1

Here are your answers

Explanation:

Let's estimate the sums and differences to the nearest whole number by rounding each number first, and then performing the calculations:

1) 82.23 + 35.23 ≈ 82 + 35 = 117

2) 58.23 + 11.34 ≈ 58 + 11 = 69

3) 73.34 + 54.35 ≈ 73 + 54 = 127

4) 73.23 + 44.5 ≈ 73 + 45 = 118

5) 60.54 - 45.67 ≈ 61 - 46 = 15

6) 53.78 - 23.56 ≈ 54 - 24 = 30

7) 51.45 - 46.78 ≈ 51 - 47 = 4

8) 10.43 + 11.78 ≈ 10 + 12 = 22

9) 56.45 + 16.45 ≈ 56 + 16 = 72

10) 94.78 + 78.12 ≈ 95 + 78 = 173

11) 53.23 - 12.85 ≈ 53 - 13 = 40

12) 99.78 - 6.58 ≈ 100 - 7 = 93

13) 73.56 - 36.18 ≈ 74 - 36 = 38

14) 81.56 - 3.56 ≈ 82 - 4 = 78

15) 65.78 - 46.34 ≈ 66 - 46 = 20

Please note that these are rounded estimates

Answer 2

Okay, first we need to round each number to the nearest whole number before performing the addition or subtraction. Here are the rounded sums and differences:

1) 82 + 35 = 117

2) 58 + 11 = 69

3) 73 + 54 = 127

4) 73 + 45 = 118

5) 61 - 46 = 15

6) 54 - 24 = 30

7) 51 - 47 = 4

8) 10 + 12 = 22

9) 56 + 16 = 72

10) 95 + 78 = 173

11) 53 - 13 = 40

12) 100 - 7 = 93

13) 74 - 36 = 38

14) 82 - 4 = 78

15) 66 - 46 = 20
