It looks like you've added a couple more questions to section 3. Let's solve them.

3. Write the following decimals. Round your answer to 2 decimal places.

Part a· 2 steps

727\frac{72}{7}

  1. Divide the numerator by the denominator.

    727≈10.2857...\frac{72}{7} \approx 10.2857...

  2. Round to 2 decimal places.

    The third decimal place is 5, so round up the second decimal place.

    10.2857...≈10.2910.2857... \approx 10.29

    The rounded decimal is 10.29\boxed{\text{10.29}}.

Part b

15.25\text{15.25}

614\frac{61}{4}

  1. Divide the numerator by the denominator.

    614=15.25\frac{61}{4} = 15.25

  2. The decimal already has two decimal places, so no rounding is needed.

    The decimal is 15.25\boxed{\text{15.25}}.
