Answer 1

We have to solve $3.72-2.19$

Step 1: Convert into like decimals

We can convert unlike decimals into like decimals by adding zeros to the right of the decimal parts.

Here they are like decimals. So no need to convert.

Step 2: Write the decimal number under other decimal numbers so that the decimal points of both the decimal are in the same column. The digits having the same place values should be in the same column. Then subtract as the subtraction of whole numbers.

$$\begin{gathered} 3.72 \\ -2.19 \\ \_\_\_\_\_\_\_ \\ 1.53 \\ \_\_\_\_\_\_\_\_ \end{gathered}$$

Hence, $3.72-2.19=1.53$
