Question

question 2 (1 point)
round to the nearest thousandth.

1. 0.1245
2. 7.21973
3. 456.25478

a 6. 0.125 7. 7.220 8. 456.255
b 6. 0.13 7. 7.22 8. 456.26
c 6. 0.1245 7. 7.2197 8. 456.2548

Explanation:

Step1: Round 0.1245 to nearest thousandth

The thousandth place is the third decimal digit (4). The next digit (5) is ≥5, so we round up the thousandth place: \(0.124 + 0.001 = 0.125\)

Step2: Round 7.21973 to nearest thousandth

The thousandth place is 9. The next digit (7) is ≥5, so we round up the thousandth place: \(7.219 + 0.001 = 7.220\) (we keep three decimal places)

Step3: Round 456.25478 to nearest thousandth

The thousandth place is 4. The next digit (7) is ≥5, so we round up the thousandth place: \(456.254 + 0.001 = 456.255\)

Answer:

A. 6. 0.125 7. 7.220 8. 456.255
