Answer:

  • 360
  • 4.21

Explanation:

You want the answers expressed to the appropriate precision for ...

  • 410 -52
  • 3.054 +1.16

Rounded to tens

The least precise number in the sum is 410, apparently rounded to the tens place. (If the 0 were significant, the number would be written with a decimal point: "410.".) The sum needs to be rounded to the same precision:

410 -52 = 358 ≈ 360

Rounded to hundredths

The least precise number in the sum is 1.16, apparently rounded to hundredths. The sum needs to be rounded to the same precision:

3.054 +1.16 = 4.214 ≈ 4.21
