Question

Write the name of number $3.15$ in two ways ?

Answer 1

Step 1:Say the number before the decimal point first:

Decimal numbers are read left to right, just like normal numbers. Always start with the number that is to the left of the decimal place. This is the "whole" number. Here the whole number is $3$.

Step 2:Read "and" as the decimal point:

The period, or decimal point, in the number can simply be read as "and." Say the decimal directly after the number that is in front of it, or else it can get confusing. The decimal point determines which numbers are whole numbers and which numbers are not.

Step 3:Identify which place the last number is in after the decimal:

It is important to be accurate when you are describing numbers in maths. Determine which place the last number after the decimal is in by counting how many digits to the right of the decimal a number is. Then, add a $0$ for each digit to the right. Common decimal numbers end in the tenths, hundredths, or thousandths.

Here in the number $3\dot{}15,5$ is in the hundredth place

Hence, the two ways in which number can be named as,$1$. Three and one-five hundredth $2$.Three point one five
