Answer:
1.6, 2.4, and 3.1.
Explanation:
Identify the tenths digit: 6 in 1.6.37
Identify the next smallest place value. There is nothing next to the 6.
Is that digit greater than or equal to five? No, so round down.
The tenths digit stays the same at 6. Since the remaining digits are after the decimal point you just drop them.
