Question

sarina rounded a number to the nearest whole number and got 7. which number could be the number sarina rounded to the nearest whole number? a 7.3782 b 7.6581 c 7.9275 d 8.3497

Explanation:

Step1: Recall rounding rule for whole numbers

A number rounds to 7 if its value is $\geq 7.0$ and $<7.5$ (since we look at the tenths place: if tenths digit is <5, we round down to 7; if $\geq5$, we round up to 8).

Step2: Check each option

  • Option A: $7.3782$: Tenths digit is 3 <5, so rounds to 7.
  • Option B: $7.6581$: Tenths digit is 6 ≥5, rounds to 8.
  • Option C: $7.9275$: Tenths digit is 9 ≥5, rounds to 8.
  • Option D: $8.3497$: Tenths digit is 3 <5, rounds to 8.

Answer:

A. 7.3782
