During a mountain expedition, Emek and Luna followed a trail marked with decimal number cards leading to supply checkpoints. After a strong wind scattered the markers, they found the cards labeled 6.407, 6.470, 6.074, 6.417, and 6.700. They carefully read each decimal, wrote the missing trailing zeros where helpful for comparison, and ordered the markers from least to greatest before placing them back along the trail. The restored checkpoints guided their hiking team safely to the campsite before nightfall.

Hint
Compare the digits from left to right, starting with the tenths place.
A hiker says that 6.470 is greater than 6.700 because 470 is greater than 700. Which statement is correct?
The hiker is incorrect because 6.700 has 7 tenths, which is greater than 4 tenths.The hiker is correct because 470 is greater than 700.The two decimals are equal because they both start with 6.The two decimals cannot be compared.Correct! The tenths digit determines that 6.700 is greater than 6.470.
Compare the place values from left to right instead of treating the decimal part as a whole number.
Next🎉 Congrats! You got this question!
Hint
First arrange all five decimals from least to greatest, then count the numbers after 6.417.
After ordering the markers from least to greatest, how many markers come after 6.417?
Correct! Two markers come after 6.417.
Write the decimals in order before counting.

Hint
Compare the tenths, then the hundredths and thousandths digits when needed.
Which list shows the decimal markers in the correct order from least to greatest?
6.074, 6.417, 6.407, 6.470, 6.7006.074, 6.407, 6.417, 6.470, 6.7006.407, 6.074, 6.417, 6.470, 6.7006.074, 6.407, 6.470, 6.417, 6.700Correct! The decimals are arranged from least to greatest.
