Question

Rainfall collected in a rain gauge was found to be (estimate) 7.4 cm whenrounded to the nearest tenth of a centimeter. Choose all possible valuesthat would have resulted to that estimate. *7.351 cm7.449 cm7.452 cm7.295 cm

Answer 1

Looking at the given figures, an estimate of 7.4 would mean the original number was 7.4 cm and the digit after 4 was below 5 or the original number was 7.3 and the digit after 3 was greater than or equal to 5

Therefore, the possible values that would have resulted to that estimate would be

7.351 cm

7.449 cm
