Write 2.07, 2.7, 2.007 and 2.77 in increasing order. Which number lands in the THIRD position?

Comparing decimals is just comparing place values left-to-right. To make it easy, give both numbers the **same number of decimal places** by adding zeros on the right (which never changes the value). Compare 1.4 and 1.42: rewrite 1.4 as 1.40. Now compare digit-by-digit — 1.40 vs 1.42 → at the hundredths place, 0 < 2 → 1.4 < 1.42.
