Question

a bag of rice originally came with 27 ounces of rice. a jumbo bag contains 20% more. how many ounces of rice does the new jumbo bag come with? set up the double number line to show that 27 ounces is 100%.

Explanation:

Step1: Find 20% of 27

To find 20% of 27, we calculate \( 0.20 \times 27 \).
\( 0.20 \times 27 = 5.4 \)

Step2: Add to original amount

The jumbo bag has 20% more than 27 ounces, so we add the 20% amount to 27.
\( 27 + 5.4 = 32.4 \)
We can also calculate it as \( 27 \times (1 + 0.20) = 27 \times 1.20 = 32.4 \)

Answer:

The new jumbo bag comes with 32.4 ounces of rice. For the double number line, the top number line (ounces) will have 32.4 at the end (since 27 is 100%, and 32.4 is 120% of 27), and the bottom number line (percentage) will have 120% at the end.
