Question

Use the digits 3,7, 1 and 5 to write a number that rounds to each of the following 1700, 3500, 1600, 7400

Answer 1

1735 rounds to 1700
3517 rounds to 3500
1573 rounds to 1600
7351 rounds to 7400

Answer 2

1700, 3517, 1573, 7351

Explanation:

1735 ≈ 1700 [ 35 is less than 50 so after round off 35 will be considered as 00]

3517 ≈ 3500 [Since 17 is less than 50 therefore, after round off 3517 will become 3500]

1573 ≈ 1600 [73 is more fifty so it will be considered as 100 as a whole number and 1573 will become 1600 ]

7400 ≈ 7351 [Since 51 is greater than 50 so it will be considered as 100 and 7351 will become 7400 after round off]
