Answer 1

Here we have 1 tower of 100 small squares at hundreds place, 1 block of 10 small squares at tens place, nothing at one’s place, and 4 parts of a small square (each small square block is also divided into 10 equal parts) at tenths place.

So, the correct decimal is:
1 × 100 + 1 × 10 + 0 × 1 + 4 × ($\frac{1}{10}$)
= 100 +10 + 0 + 0.4
= 110.4

Hundreds	Tens	Ones	Tenths	Number
1	1	0	4	110.4
