At an abandoned explorer camp, Emek and Luna discovered four torn map fragments labeled 6.342, 6.324, 6.4, and 6.348. A faded note said the fragments belonged from lowest coordinate to highest. Emek rewrote 6.4 as 6.400 so every number could be compared through the thousandths place. Luna compared the tenths first, then the hundredths and thousandths when needed. Together they ordered the fragments as 6.324, 6.342, 6.348, and 6.400. When they joined the pieces in that order, a trail line appeared across the completed map. It pointed east toward their camp, and they followed it safely home.

Hint
Compare the digits from left to right and find the first place where the two numbers differ.
Emek says 6.342 is greater than 6.348 because 2 is greater than 8 in the ones he is comparing. Which statement correctly checks his reasoning?
Emek is correct because 2 is greater than 8.Emek is correct because both numbers have 6 ones.Emek is incorrect because 6.342 and 6.348 are equal.Emek is incorrect because the numbers first differ in the thousandths place, where 2 is less than 8.Correct! The numbers first differ in the thousandths place, and 2 thousandths is less than 8 thousandths.
Try again. Compare 6.342 and 6.348 one place at a time from left to right.
Next🎉 Congrats! You got this question!
Hint
Think of the decimal parts as 342 thousandths and 324 thousandths.
Luna compares 6.324 and 6.342. How many thousandths greater is 6.342 than 6.324?
Correct! 6.342 is 18 thousandths greater than 6.324.
Try again. Find the difference between 342 thousandths and 324 thousandths.

Hint
Compare 6.345 with the nearby coordinates 6.342 and 6.348.
A fifth map fragment is labeled 6.345. Where should it be placed so all the fragments remain ordered from lowest coordinate to highest?
Between 6.342 and 6.348Between 6.324 and 6.342Between 6.348 and 6.400After 6.400Correct! 6.345 is greater than 6.342 and less than 6.348.
Try again. Compare the thousandths digits after noticing that the other digits are the same.
