The next wave knocked off the boat,

Question

a gold coin, which sank to −7
4
feet below the surface.

a bronze coin, at −1
4
foot.

a silver coin, which landed on the diving raft at 3
2
feet.

a copper coin, at −11
4
feet.

Locate the treasures on the number line. Which one is highest?

Answer 1

To locate the treasures on a number line, we need to convert each measurement into decimal form for easier comparison.

1. Gold Coin: \(-7 \frac{4}{10} = -7.4\)

2. Bronze Coin: \(-1 \frac{4}{10} = -1.4\)

3. Silver Coin: \(3 \frac{2}{10} = 3.2\)

4. Copper Coin: \(-11 \frac{4}{10} = -11.4\)

Now we have the following decimal values:

• Gold Coin: -7.4 feet
• Bronze Coin: -1.4 feet
• Silver Coin: 3.2 feet
• Copper Coin: -11.4 feet

Next, we can locate the coins on a number line:

• Copper Coin is at -11.4
• Gold Coin is at -7.4
• Bronze Coin is at -1.4
• Silver Coin is at 3.2

Highest Treasure

The highest treasure is the one with the greatest value. In this case, the Silver Coin at 3.2 feet is the highest treasure.
